You have to laugh. They were clearly pinning all their survival hopes on him finding some form after returning from injury, and almost immediately he gets himself suspended for three games. If it was anybody else they would have just accepted the FA ruling and moved on.
He thought he was being cute and clever, deliberately swinging his arm at Flores but trying to make it look like it was unintentional, but as people have already noted it is the facial expression that gives it away.
As for Flores' play-acting though - what a prize c*nt.
