I think he has reason to complain in the sense that those are given more often than not, but I don't see that as a penalty. It's not dangerous or malicious, he plays the ball and doesn't really impede the player.
Yeah they basically just went after City like they were any old team. Made for a fun match, they scored a couple of nice goals, and was better than watching a team hold out for a half and then concede three without reply.
