If Barca doesn't trade Messi within the next transfer window in January, than he's gone in a free transfer. He will not sign a new 5 yr contract even if DiMaria and Dembele come.
So I think Messi will go to Man city in 5 mths after paying the €300MM rekease fee or Messi rly fucks over Barca and waits til the summer.
It is absolutely bonkers if they don't trade him. The new contract he hasn't signed is less than what neymar got from psg, so he's definitely not signing that. All I know is, Messi will be the star at Man City and he'll make Jesus his new bitch. (Geez that sounds blasphemous.)
New Barca?
Dembele + Suarez + Dimaria
