Sunderland boss Roy Keane has banned his players from swapping shirts with the opposition.
"It's understandable if a young player does it at the end of a game but it's ridiculous when you get a senior player asking you during a game. It happens. I remember when it has happened to me and I've been thinking 'Are you focused on the game at all?'
"There have been people through my career who have been more focused on getting someone's jersey.
"You see players now who say 'I've got 50 jerseys in my garage'. I think 'Yeah, brilliant, but how many medals have you got?'
"I certainly wouldn't expect any of our players to be doing anything like that.
"I don't think there's that feeling among our group.
"We've earned the right to be in the Premier League and we don't need to be star-struck by anyone."
