Sunderland manager David Moyes could reportedly land in hot water with the Football Association after his exchange with referee Bobby Madley in the tunnel of Saturday's defeat to West Ham United.
The 53-year-old was furious with the Hammers' 94th-minute goal as he believed that two players were offside when Winston Reid scored the winner at the London Stadium.
After the final whistle, Moyes reportedly confronted Madley in the tunnel, which could result in the FA taking action if the match official mentions the incident in his report, according to The Mirror.
The Black Cats are currently rooted to the bottom of the Premier League table after picking up just two points from nine games.
