Vasilevskiy
The cat will be back
And if you had common sense you would know that injuries prevented him on becoming the GOAT.
He is possibly the best candidate of "what if".
Ronaldo El fenomeno earlier in his career was way more dangerous than Messi ever was. He was direct, fast, technical, powerful and a lethal finisher. He would come at you at full speed, with technique and power and he won ballon d'or very early in his career too (younger than Messi).
Anyway I get from your comment that you probably have never watched him at all play other than possibly late in his early retirement form.
Woah let's calm down there. Watch some 11-12 Messi games
