Tony Pulis has called for lifetime bans for any West Bromwich Albion fans found guilty of contributing to Saturday's problems at Aston Villa.

Pulis would support lifetime bans for any of the club's fans who were found to be responsible for throwing seats during the chaotic conclusion to the FA Cup defeat at Aston Villa as the Football Association prepares to investigate.

Pulis said: "If that was the situation, and they've got CCTV cameras up there, those supporters should never come into another football ground. It is like people coming into someone else's house - you have to show respect."

Pulis was also concerned about the ease with which spectators were able to get on to the pitch.

He added: "I am old enough to have seen isolated incidents happen like that. I don't want to have a go and take anything away from what happened on the pitch and what happened in the game.

"If one thing, Villa should look at the stewarding because with a game at this time of night, 5.30pm, you need to police it properly, and I am sure Villa will look at it."
