The football before a World Cup semi-final is usually simple enough: get the best players on the ball and hope the moment does not swallow them. But Sergio Aguero has pointed to something less glamorous and potentially far more decisive. According to the former Argentina and Manchester City striker, Argentina's unity could be the crucial edge when they face England tonight in Atlanta.
That is not the sort of theory that shows up on a team sheet, but it is exactly the kind of detail that can shape a knockout tie. Argentina arrive as the holders, having survived scares against Cape Verde and Egypt before edging past Switzerland in extra-time in the quarter-finals. England, meanwhile, are here after a dramatic win over Norway, with Jude Bellingham scoring twice and Harry Kane continuing to give the Three Lions serious attacking force.
Why Aguero thinks Argentina have the edge
Aguero's point was straightforward enough. He said England do not usually look like a very united team in the way Argentina do, not because the players do not get along, but because the structure is different. In his view, English players may go to training, do the job and head home, while Argentina's group is far tighter, more familiar and more connected on the pitch.
That matters, he argued, because Argentina's players are close-knit and friendly, which reduces the chance of anger or bad blood inside the camp. And in a game of this size, that kind of harmony can be a real weapon. When pressure rises and the match starts to tilt, groups either stay together or come apart. Aguero's argument is that Argentina stay together better than most.
He also suggested that England can become more combustible when things are not going well, with players starting to argue and conflict creeping in. That is the uncomfortable bit for England supporters: not that the talent is lacking, but that the emotional temperature can rise at exactly the wrong moment.
Messi, Kane and the weight of the occasion
The other obvious factor is the stars themselves. Lionel Messi is in strong tournament form with eight goals and two assists, and Argentina will expect him to be central again if they are to reach the final. England, for their part, have relied on Harry Kane and Jude Bellingham to carry a huge share of the attacking load. On paper, this is a heavyweight semi-final. In practice, it may be decided by who handles the tension better.
Thomas Tuchel's description of England as lucky, and having made life difficult for themselves, adds another layer to the debate. It is a blunt assessment, and one that fits the broader picture: England may have the firepower, but they have not exactly cruised into the final four.
So this is where the real argument sits. Argentina have the tournament pedigree, the close-knit group Aguero keeps talking about and a Messi who looks in top form. England have weapons of their own, but they now have to prove they can keep the team shape and the team mood intact when the stakes go up again. That is a very different test from surviving a quarter-final. And it is the sort of test that exposes whether unity is just a nice talking point or, as Aguero insists, something crucial.
By the time the final whistle goes at Mercedes-Benz Stadium, one of these sides will have a ticket to face Spain. The other will be left wondering whether talent was enough. Aguero's answer is clear: in this sort of match, maybe it is not.
