Each time anti Messi fans are comparing Messi with Ronaldo they always always quick to say that Messi should move our of Barcelona to other leagues if he will perform well like Ronaldo
Honestly I don't understand why people criticize the decision of a player who has decided to pledge his allegiance, life, and achievements to Barca. Even Ronaldo has dared Messi to come out of Barcelona and play the challenges of other leagues just as he has been doing.
Look at players like Gerard, Giggs and Francisco Totti, these were players who remained in one club yet they are considered legends. Even the so called legendary Pele never played in many leagues. He only played most of his career in Santos in the Brazilian league yet he's described as the greatest footballer ever
Even if Messi wants to leave Barcelona for real, would they even allow him? A player whose absence grossly affects the performance of the team. A player whose glory rest on Messi.
I really don't know when it come a norm that a player has to move from one club to another to prove he's the greatest.
So if Messi changes club, what does he have to prove?
