Portsmouth head coach apologizes after fan incident involving Cardiff players at Fratton Park

Portsmouth head coach John Mousinho has apologized to Cardiff City players after a fan-player incident at Fratton Park. In the 72nd minute of Portsmouth's 2-0 Championship win over the Bluebirds, Cardiff defender Krystian Bielik got into a physical altercation with a fan as he went to retrieve a ball. Cardiff head coach Brian Barry-Murphy claimed that Bielik 'got slapped in the face', while clips showed the Poland international grabbing a young fan around his upper body. Several Portsmouth supporters made gestures indicating they believed the fan had been grabbed around the throat. In the aftermath, another fan threw a ball at the head of Cardiff defender Perry Ng, resulting in both fans being ejected. Speaking after the match, Pompey boss Mousinho said: 'The referee said that, as Krystian went to get the ball, there was a little bit of a kerfuffle and one of the supporters struck him. It wasn't a good incident. I have just seen him there, and he was OK, but that's not the point, we can't be having that. We want to create a really difficult atmosphere at Fratton Park, we have done that successfully over the past few years. Sometimes it tips over, I understand that, I don't think it needs to tip over to that extent. We extend our apologies to the players, Cardiff and make sure we can try to cut it out.'
