Jong Ajax shows reserve sides belong in Dutch professional football

Key takeaways

• Dutch reserve teams play in the Eerste Divisie, which means young players on professional contracts face senior opponents without leaving their parent club.
• A player can move between a first team and its Jong side inside one club, with no transfer, no loan agreement and no fee.
• The main cost of the system falls on independent second-tier clubs, which share a league with sides that cannot be promoted.
• The case for reserve teams depends on evidence about player development that is not set out publicly in a consistent form.

Reserve teams are a squad-building tool that justifies its cost

Google search data from the Netherlands shows interest in Jong Ajax and in several fixtures involving Dutch reserve sides: Jong Ajax against De Graafschap, Jong Utrecht against Roda JC, and Jong PSV against Dordrecht. That data does not show the results of those matches, and this article does not deal with them. It deals with the structure that puts these fixtures on the calendar.

In most European leagues, a club with a promising 18- or 19-year-old has to choose. It can keep the player in the first-team squad, where he may rarely play. It can send him to the under-21s or under-23s, where he plays against people his own age. Or it can loan him to another club, which means negotiating terms, giving up day-to-day control of his development and hoping the borrowing club picks him. The Dutch model adds a fourth option. The parent club fields a second team in the professional second tier, and the player gets competitive senior football while staying within the club's own coaching, medical and contractual setup.

The argument here is that this option is worth having. For clubs whose model depends on developing players and then selling them, which describes much of the top of Dutch football, the Jong team is part of how the transfer business works. The structural costs to other clubs are real. They are smaller than the benefit, and better rules could reduce them.

Movement inside one club removes the friction of a loan

The first piece of evidence is about mechanism. A loan is a three-party arrangement between the parent club, the borrowing club and the player. It has to be negotiated, registered and usually fitted into a transfer window. It often includes terms on wage contributions, playing time and sometimes recall rights or option clauses. Each of those terms is a point where interests can clash. The borrowing club wants results this season, while the parent club wants the player's long-term development.

A Jong side avoids almost all of that. The player is already under contract with the parent club. Moving him from the first-team squad to the reserve team, or back again, is an internal selection decision, not a transfer. Nobody has to agree a fee and nobody has to sign new paperwork. If the first team suddenly needs a full-back, the coaching staff can call up the player they have been watching every week, not one who is on loan elsewhere and may be hard to recall.

This matters for squad building because it lets a club carry more professional contracts than its first team could otherwise use. A larger group of contracted young players is more useful when there is a competitive league for the ones outside the matchday squad. Without that league, a club either cuts the group back or accepts that some contracted players will stand still.

The league has eligibility rules that limit how reserve and first-team players can be used, including restrictions on older or established players dropping down. The exact terms have changed over time and are not set out in this article. The principle is that the reserve side should be a development team, not a second senior squad.

Senior opposition develops players in a way youth football cannot

The second piece of evidence comes from the opponents themselves. De Graafschap, Roda JC and Dordrecht are established professional clubs with senior squads, paying supporters and something to play for every week. Facing them makes demands that an age-group league usually does not: physical duels with experienced players, crowds, travel, and opponents whose careers depend on the result.

For a young player the difference is more than intensity. Youth matches tend to be played against opponents built and coached in a similar way. A senior second-tier side may set up to defend deep and play directly, waste time when ahead, or target a young full-back it sees as a weak point. Dealing with those problems is part of becoming a professional, and the Eerste Divisie provides them every week.

Each fixture also sets the two sides a tactical problem that reflects the structure. A reserve team usually plays the same system as its first team, so that players can move up without relearning their roles. That tends to mean an emphasis on possession and positional structure. An independent opponent can prepare for that system and set out to disrupt it. The reserve side has to solve the problem with players who are, by design, still learning. That is the purpose of the arrangement.

The development route supports the selling-club model

The third piece of evidence links development to the transfer market. Dutch clubs operate in a league with lower broadcast income than the biggest European competitions, and many of them depend on selling players to balance their budgets. In that model, a player's value at the point of sale depends partly on proof that he can perform in senior football.

A reserve team in a professional league produces that proof inside the club. Scouts from buying clubs can watch an academy graduate against senior opponents. The parent club can show a record of professional appearances and keep control of when and how the player is introduced to the first team. When an offer arrives, the selling club negotiates from a position where the player's senior experience was gained under its own contract and supervision, not partly at another club during a loan.

That does not mean every player who comes through a Jong side is sold, or that the reserve team causes any particular sale. The point is structural. The system lines up the parent club's development spending with the evidence that buyers look for. For clubs such as Ajax, PSV and Utrecht, which all field reserve sides, that alignment is a commercial asset as well as a sporting one.

The strongest case against: a league shared with teams that cannot win it

The best objection is about competitive integrity, and it deserves to be stated fully. Reserve teams in the Eerste Divisie cannot be promoted to the Eredivisie, because they would then be in the same division as their own first team. This means the league table includes sides whose final position does not decide promotion in the normal way. If a reserve team finishes in a promotion place, the place goes to the next eligible club. A league is supposed to be decided by the clubs competing for its prizes, and in this one some of the participants are not competing for them.

There is a second problem. A reserve side's strength can change from week to week depending on decisions made elsewhere. If the first team has an injury crisis, the Jong side may lose its best players overnight. If the first team has a light week, players returning from injury or short of minutes may drop down. Eligibility rules limit this, but cannot stop it altogether. An independent club fighting for promotion might face a much stronger or much weaker version of the same opponent than a rival did a few weeks earlier, for reasons unrelated to either match.

Third, there is the commercial cost. An independent club's income depends partly on home attendances and away followings. A reserve team usually brings few travelling supporters and, at home, often plays in a small stadium or training complex. Each league place given to a reserve side is a place that could have gone to an ambitious independent club from lower down the pyramid, with its own community and its own wish to rise through the divisions.

Finally, critics argue that loans can sometimes be better for development, because a loaned player has to win a place in a team that needs results. That pressure is hard to reproduce in a side whose main purpose is development.

These objections are serious. They do not show that the system fails overall, but they show that its costs fall mainly on clubs that get none of its benefits.

Evidence on player pathways would settle the question

The conclusion here could be overturned by specific evidence. If systematic analysis showed that players developed in reserve teams reach and stay in senior football at lower rates than comparable players sent on loan, the main development argument would fail. If there were evidence that reserve-team results had regularly changed the outcome of promotion races, the integrity objection would weigh more heavily. If independent second-tier clubs were shown to be financially damaged by the arrangement, and not simply losing the occasional large away following, the commercial case against would become hard to dismiss.

Comparisons with other countries would also help. Spain lets B teams play in its lower professional and semi-professional tiers, under rules that stop them playing in the same division as their first team. Germany has generally placed reserve sides in its regional leagues, below the professional divisions. A careful comparison of player outcomes and lower-league finances across these models would show whether the Dutch approach is better, worse or just different. That evidence is not set out here, and as far as this article can establish, it is not publicly available in a consistent form.

Until such evidence appears, the case rests on mechanism. For clubs that depend on developing and selling players, Jong teams make squad management simpler, move players between levels without the friction of loans, and give academy graduates senior football. The costs to independent clubs are real and should be addressed through eligibility and competition rules, not by removing reserve teams from the league.
