FA Cup: Wigan to investigate pitch invasion after Manchester City tie

Chairman David Sharpe says Wigan will work with the Football Association and police to review the pitch invasion after their win over Manchester City.

City's Sergio Aguero had an altercation with a fan after the FA Cup tie, and has since claimed he was spat at and sworn at during a post-match confrontation.

Some supporters ripped out advertising boards and threw them towards police.

The FA will study the referee's report and review available footage.

Police say two arrests were made on suspicion of affray following an incident outside the ground.

"Football is a family event and the disruption that players and fans alike faced will not be tolerated," said Greater Manchester police chief superintendent Stuart Ellison.

"As soon as people were on the pitch, we immediately deployed our resources to the front of the stands, where they were able to keep the two groups of supporters apart and prevent any further disruption."

Sharpe told BBC Radio 5 live they will look at "who was responsible for what, and will take action if we need to".

Will Grigg's goal defeated a City side that had Fabian Delph sent-off in the first half for a foul on Max Power.

The result ended City's hopes of winning a Quadruple of the Premier League, FA Cup, League Cup and Champions League.

The visiting side's players were escorted off the field after the final whistle as Wigan fans ran onto the pitch to celebrate.

Television footage appeared to show Aguero pushing a supporter away after being approached on the pitch.

"In the aftermath straight after the game you're looking at the scenes and their set of supporters and our set of supporters," said Sharpe.

"Football is an emotional game, it can do strange things to people, and last night that seemed to be the case."

In a statement, Wigan chief executive Jonathan Jackson said the club "were disappointed with the action of a minority of supporters who acted in an inappropriate manner" and "will conduct a full investigation".
