Not too many problems? Well, apart from abusing Manchester City manager Manuel Pellegrini in the crudest terms earlier this season, a two-match touchline ban for pushing assistant referee Peter Kirkup during a game against Tottenham Hotspur in August 2012 and a £10,000 fine for an altercation with Arsenal's Arsene Wenger when he was manager of West Ham United in 2006. No. Not too many problems at all.
Perfect reason to dismiss him. Not got a leg to stand on in court if he so chooses to go that way.
