Not a chance Aimar excels in the modern game. He plays in a position that doesn’t really exist anymore and he pretty much has no athletic abilities that are needed in the modern game.
Kevin Keegan and Ian Rush would absolutely excel.
Both had massive physical gifts, technically great and were pressing from the front before it was a thing.
The likes of Cruyff, Maradona and original Ronaldo would be absolutely insane. The space they are given, not having career ending tackles thrown at them every game and being so technically proficient would make the modern game a breeze.
