Wigan recorded a surprise 1-0 win over Manchester City in their FA Cup clash, but it didn’t come without incident.

The match was pretty normal up until the end of the first half, when City’s Fabian Delph was sent off for a rash challenge on Wigan’s Max Power.

Referee Anthony Taylor first pulled out a yellow card from his pocket. Then he changed his mind and produced a red card.

That infuriated City players, who surrounded the referee, and the dispute spilled into the rival technical areas with Sergio Aguero having to be dragged away by Guardiola as he argued furiously with Wigan coaches.

The scene turned even uglier, with television cameras in the tunnel capturing footage of City manager Pep  Guardiola and Wigan manager Paul Cook in a major verbal confrontation and being kept apart by staff.

Guardiola had to be pulled away from his Wigan counterpart  as the pair engaged in a heated row as they headed down the tunnel at half-time.

After the match in which Wigan’s only shot at the goal was fatal to City’s aspirations for the season, excited Wigan fans  invaded the pitch to taunt City players, with Sergio Aguero one of the targets.

One fan attempted to punch the striker, but  Aguero brushed him away before Wigan defender Cheyenne Dunkley, City coach Mikel Arteta and physiotherapist Steven Lilley rushed to the Argentine’s aid.

Aguero followed the fan and Lilley pulled the forward away before he could retaliate.

Wigan chairman David Sharpe denounced the actions of the supporters. ‘It’s not nice to see,’ he said. ‘Football is emotional, it’s what it does to fans. But I don’t like to see this at the end of the game. It is a massive result, but we have to stay classy in football. I don’t like what I am seeing here.’

Wigan manager Paul Cook added: ‘It’s not right, it’s not correct, player safety is paramount.’
