Wigan Athletic chairman David Sharpe has stated that the club will work with the FA and police to review the post-match trouble after their 1-0 win over Manchester City in the FA Cup.
Man City's Sergio Aguero had an altercation with a fan after the tie amid a pitch invasion, while some supporters ripped out advertising boards and threw them towards police.
The FA say they are reviewing the match referee's report and studying all available footage while Wigan chairman David Sharpe has confirmed they will investigate what happened.
He told BBC Sport: "The emotions of football can sometimes get the better of fans and that was evident last night. I don't like to see what happened at the end of the game.
"We'll have to look into it properly with the FA and the authorities over what was going on, but it looks like both City and Wigan fans weren't being too pleasant to each other, and there was damage to the stadium.
"But that can be emotion of supporters sometimes. Things can get carried away. We've got to remain classy in certain situations and that's the feeling we're taking from last night.
"I don't think it will detract from our victory - not one bit. I think people know how football is and what fans can do in a certain moment, they can get carried away.
"I think the main story is Wigan beating Man City, who were on for the quadruple. They're favourites for the Premier League, the Champions League - and a League One club has just knocked them out of the FA Cup."
