Didn't they come bottom of the league last season? I totally get why someone would go and play MLS, I honestly think that for a brilliant player who has spent years playing high pressure, high stakes games against the top players in the world, it could be a lot of fun to go and play in a league like that. Basically treat it like a kick-around with your mates, start enjoying your football again etc etc And maybe he could earn more money in Saudi Arabia or China or something, but he already has all the money he could need so why not go somewhere where it won't be such a culture shock, he speaks the language and it's just more fun to live? But all that said, why go to a team in that league without a proper stadium? That seems weird.
I totally get where the keeper is coming from though, if someone said Mess is thinking about joining in my Monday night friendly games I'd think that we weren't ready but I'd definitely still want him to play.
