"Considering they could have any player in the world with the money they've got. They have got some s**** players Man city," he tweeted.

Barton also ranted at the Citizens' fans, claiming to have a poor opinion of them after accepting Carlos Tevez back into the fold following his six-month absence last season.
He added: "Like they give a s*** about the fans. I lost respect for their fans when the took back Tevez with open arms after his self imposed exile. He even had the audacity to celebrate a goal with a golf swing in front of you all. And you lapped it up
"Fickle, fickle, football fans... #howsad"
