No, he quite simply cannot be as flexible as the others because he can't play on the wing. That's not a matter of opinion. He can't play across the front 3, and the others all can, and could end up like Sturridge at Liverpool. Sturridge is the best forward Liverpool have, and he's by far the best finisher, but he was dropped because he can't play fluidly like Mané, Firmino and Lallana can.
Aguero also hesitated in front of goal a few times, let hismself get forced out wide because he didn't want to shoot and butchered two separate 3v2 breaks where he could have Sané through against the keeper but inexplicably did not.
He worked hard but he's also not scored against any league opposition in the top 10 all season. He's got one in his last 5, and for every game where he's working hard and positive, there's one where he's sulking and looks like he'll get himself sent off again.
It would be stupid to think Aguero is not just as much on the chopping block as anyone else in the team.
