We are talking about Messi now?? lol
World football would explode if Messi and Ronaldo played in the same team. Anyway we can't sign him, not only because he likely won't leave, but because we are already financially stretched with Ronaldo and Messi would earn even more.
Forget about Dybala, if Messi is here with Ronaldo we better stock up on workhorses cause he does 0 defense and running.
