I would like to see Messi change leagues more so I can see him play for another team besides Barca. I think there are big advantages his teammates provide him that he would get in few teams.
I mean, to see 3 or 4 players running in behind the defense when Messi has the ball is quite staggering. It would be hard to defend anyone when there are 3 or 4 of his teammates trying to run in behind you, let alone Messi.
Barca wins the ball back so quickly, Messi doesn't have to do any defensive work. There are acres of space between the lines in Spain except against Atl. Madrid whom Messi struggles with the most.
Messi might be one of the top 3 players ever but I'd like to see him on another team before I can say that for sure.
