Sunderland have confirmed Darron Gibson will face an internal disciplinary process after he was filmed appearing to criticise team-mates after Saturday's 5-0 friendly loss to Celtic.

Midfielder Gibson, 29, has been at Sunderland since joining from Everton in January, making 12 appearances.

"Darron Gibson has not conducted himself in a manner befitting Sunderland AFC," a club statement said.

"We will initiate our internal disciplinary process."

The statement added: "Darron has apologised this (Monday) morning."

In the video, which was filmed in a bar by supporters and posted on social media, the Republic of Ireland international described the team as "s***".

He also claimed certain team-mates "did not care" about playing for Sunderland, but maintained he was committed to the club.

Sunderland, who were relegated from the Premier League last season, begin the 2017-18 Championship campaign with a home game against Derby County on Friday.
