His career was plagued by injuries. What if he was completely healthy?

Maradona. With how protected players are now , he’d be unstoppable. The only question would be if teams could keep him out of trouble off the pitch.

Duckadam. Romanian goalkeeper. In the 1986 European cup final, blocked all 4 kicks in the pk shootout vs Barcelona.

Platini’s character, or lack thereof, showed in the “Heysel” final, when, after he scored what was going to be the match winner, he celebrated like tens of people didn’t just die before a game that, under normal circumstances, would have and should have, never been played.

As far as why he’s underrated, he did take France to two world cup semis, losing both to Germany, won a European tournament at home, while Zidane took France to two world cup finals and won one, while also winning an Euro. Of course, recency bias plays a role too. Platini’s France was almost like that 1982 Brazil team , a beautiful dream but lacked the cynicism needed to go all the way.
