Mexico's friendly with Serbia is really about selection, not theatre. Javier Aguirre gets one last proper look at his team before the World Cup opener against South Africa on June 11, and there is still enough uncertainty around the XI to make this more than a routine warmup. After a year of heavy experimentation, the final rehearsal matters because some decisions still do not look settled.
Aguirre said the squad are arriving in the right state for the tournament. He told goal.com: "I think the team is arriving in a very good physical moment. I was saying it today while watching Serbia's video - we're in our best physical, athletic, and even mental moment, because Imanol Ibarrondo [mental and leadership coach] had a couple of talks with them this week. I asked him how he felt they were, and they looked, like me, very excited. None of them has had this experience, and we're eager for the moment to arrive and for the party to begin."
That sounds encouraging, but the bigger point is simpler: this is the last meaningful chance to decide who starts when the pressure becomes real.
Why this friendly matters more than the result
Mexico play Serbia in their final preparation match ahead of the 2026 FIFA World Cup. The opener against South Africa is fixed for June 11, so the margin for further experimentation is basically gone.
Aguirre has used 54 players in 22 matches over the past year, with fewer than half making the final squad. That is a huge amount of churn this close to a major tournament. It suggests he has spent the last year testing combinations rather than locking down a settled side, and that makes the Toluca match less about momentum and more about clarity.
There is an obvious risk in that much rotation. Rhythm can suffer, partnerships can stay half-formed, and key roles can remain blurry longer than they should. Still, if Aguirre wanted one final check before the tournament starts, this is it.
There are also details from the recent run that show why the final tune-up still matters. Mexico beat Australia 1-0 at the Rose Bowl in front of 78,479 fans, and they have extended their unbeaten streak on Mexican soil to 22 matches. Those are useful signs of stability, but they do not answer every selection question by themselves.
Fidalgo has given Aguirre a genuine midfield decision
If one player has pushed this beyond a routine pre-tournament selection process, it is Álvaro Fidalgo. His role has become a serious talking point, and not just because his name is fashionable this week.
Goal.com rated Fidalgo 8/10 against Serbia and described him as elegant from start to finish. For a player trying to force his way into a World Cup midfield, that kind of display matters. Selection debates can get noisy, but good performances in the final rehearsal are hard to dismiss.
The praise around him has also come from inside the camp. Vega told goal.com: "Yes, for me, they are players who make an absolutely massive difference. Whenever I faced Quiñones, I knew he was a very important player; he has been here in Mexico for a long time. It's the same with Fidalgo, a player who defined a very important era at America. No one doubts or denies the talent of those two players."
That mention of C. Quiñones matters, but Fidalgo is the more interesting selection case because midfield usually decides how much control Mexico actually have. If Aguirre wants cleaner possession and a calmer organiser between the lines, Fidalgo has made a timely argument for himself. The issue is not whether he has talent. It is whether Aguirre trusts him enough to make him part of the first-choice shape.
Edson Álvarez remains one of the names around whom the side is naturally built, so any decision involving Fidalgo is really a question of balance and partnership rather than simple hierarchy. That is what makes this one of the more important calls.
The attack still has pressure points before South Africa
The other unresolved area is further forward. Raul Gimenez is still central to the attacking picture, and that alone tells you Aguirre has not fully spread the burden yet.
There is also the Gilberto Mora angle, which is impossible to ignore because of his age. Mora would be 17 years and 240 days old on June 11, one day older than Pele was when he set the youngest World Cup scorer record. That does not make him a guaranteed option, and it definitely does not mean any history has already been made. It does underline how unusual his situation is going into a major tournament.
Mexico averaged 11.5 shots across recent World Cup warmups against Portugal, Belgium, Ghana and Australia. The volume is decent enough, but the real question is who turns those attacks into something reliable once the tournament begins. That is where Raul's role still feels important, and why the supporting cast around him remains under review.
There are defensive details to tidy up as well. Petar Stanic scored first for Serbia after a miscommunication between Johan Vásquez and Jesus Gallardo, the kind of lapse Aguirre will want cleaned up before South Africa. One bad exchange in a friendly is manageable. In the World Cup opener, it is a different problem.
That is why this game matters. Aguirre can talk about physical and mental readiness, and he probably is right, but the bigger task is leaving Toluca with fewer doubts than he had before kickoff. Mexico open the World Cup against South Africa on June 11, and this is the last chance to settle who deserves to be on the pitch when it starts.
FAQ
Why does Mexico vs Serbia matter more than a normal friendly?
Because it is Mexico's final preparation match before the 2026 World Cup and the opener against South Africa comes on June 11. Javier Aguirre has used 54 players in 22 matches over the past year, so this game is less about the result and more about settling the starting XI and final selection calls.
Will Alvaro Fidalgo start for Mexico at the World Cup?
He has made the decision harder to ignore. Fidalgo was praised as a difference-maker, then followed that with an 8/10 display against Serbia, where he was described as elegant from start to finish. That does not guarantee a starting place, but he has clearly strengthened his case at the right time.
What is Javier Aguirre still trying to decide before Mexico's opener?
Aguirre still appears to be working through several lineup questions, especially in midfield and attack. The scale of his experimentation is clear: he has used 54 players across 22 matches in the past year, with fewer than half making the final squad. Serbia is his last meaningful look before South Africa on June 11.
Can Gilberto Mora make World Cup history with Mexico?
He has a chance to enter that conversation, but nothing has happened yet. Mora would be 17 years and 240 days old on June 11, which is one day older than Pele was when he set the youngest World Cup scorer record. The point here is possibility, not an achievement already secured.
