Tottenham boss Harry Redknapp has urged the Football Association to take action against Mario Balotelli for an apparent stamp on Scott Parker.
Redknapp was left fuming after the Italian's back-heel into Parker's head went unpunished and then he went on to score the winning penalty for Manchester City in a thrilling finish at the Etihad Stadium.
Replays were inconclusive over whether World Cup referee Howard Webb got a clear view of the incident, but if he refers the matter to the Football Association, Balotelli could be hit with a four-match ban - he has already been sent off once this season at Liverpool - that will rule him out of the Carling Cup semi-final second leg at Anfield on Wednesday.
Redknapp expects the FA to look at the incident as he feels the offence was blatantly obvious.
"I'm sure they [FA] will look at it," Redknapp said. "They must do, mustn't they? It's not the first time he's done that is it and I'm sure it won't be the last.
"The first [stamp] could be an accident, but the second one? He's back-heeled him straight in the head. I don't like talking about people kicking players in the head, but when you see that, it's wrong. It's blatantly obvious.
"Whether he gets sent off or whatever, it's wrong and I don't like seeing people react like that to a challenge.
"Scott made a good block. He [Balotelli] reacts like that at times to challenges, but Scott now has a lovely cut on his head. I don't see any reason. What reason did he have to kick Scott in the head with his studs while he is lying on the floor?
"It's not something I understand. How you can back-heel somebody in the head when they are lying on the floor?
"It's not a nice thing to do and it has no place in football."
