Diego Luna isn't going to the World Cup. The roster leaked over Memorial Day weekend and got made official on a stage at Pier 17, and his name wasn't on it. If you've watched this team for the last year and a half, you already know how strange that is.

The buildup made it worse. Nike put him at the center of the kit launch. He was in Head & Shoulders ads. Panini gave him a World Cup sticker. He posted the new jersey on Instagram with the caption

"They never plan for the wild card. Espera lo inesperado."

Then the team didn't plan for him at all.

And this isn't fans being sentimental about a fun bench guy. He scored twice inside the first 15 minutes of the Gold Cup semifinal against Guatemala. Earlier that year he took an elbow to the face against Costa Rica, broke his nose, and talked his way into staying on the field, then assisted the opening goal a minute later with cotton shoved up his nostrils. Pochettino called it big balls and great character. This spring he had four goals and three assists in nine MLS games for Real Salt Lake. He's a good player having a good run.

Pochettino refused to explain any of his cuts, said it would be disrespectful to the players who made it. So there's no official reason. What follows is what fans and pundits have actually landed on, pulled mostly from the Reddit threads where the argument hasn't stopped since the roster dropped.

  1. Reyna took his spot. This is the one everybody comes back to. Gio Reyna made the team. He scored one goal in 510 Bundesliga minutes all season and can barely get on the field for his club. Luna was the better player this year by a clear margin, and the spot still went the other way. Most people read it as a name beating production, and on Reddit it's the single most repeated complaint in the thread.

  2. Europe is superior than MLS. A lot of the argument is just that Pochettino quietly discounts MLS. Reyna plays in Germany and has a longer history with the national team, and "European experience" gets treated as a tiebreaker for World Cups. The suspicion is that Luna got marked down for where he plays, not how he plays.

  3. The self-promotion theory. A popular one online: that Luna acting like a World Cup player before he was one — the commercial, the jersey post, the "wild card" caption — annoyed Pochettino. The idea is that he put himself in the team in public before the coach put him in it for real.

  4. Pochettino wanted experience. His own stated logic is that a friendly isn't a World Cup, so he leans on players he trusts to handle the moment. Reyna has been to a World Cup. Luna hasn't. That's a real reason even if you don't buy it.

  5. The slow start. Luna had an injury before the season and came off the bench in the early games. The pre-roster window is when you make your case, and the argument is he didn't hit it running while Pochettino was deciding.

  6. Style. He makes odd runs and tries to break the game open. Reyna is more controlled. If Pochettino wants structure against Paraguay, Australia and Türkiye, you can see why he'd pick the player who stays in the plan over the one who blows it up.

  7. The Mexico thing. A more cynical take is that Luna flirting with playing for Mexico a couple years ago left a mark, even though he chose the U.S. in the end. There's no evidence for it, but people bring it up.

The honest answer is that we don't know. Every reason above is a guess, including the good ones, because the only person with the real answer won't say it. Luna's own club coach, Pablo Mastroeni, called it an interesting decision and said the obvious thing — that in a tournament where you want a player the moment doesn't get too big for, Luna fit.

This isn't new for him either. They left him off the Olympic team last summer and he had a goal and three assists against Atlanta United the next weekend. He also could have played for Mexico and chose the U.S.

So we get a World Cup without him. I think it's a mistake. We'll find out in June whether Pochettino did.
