Things just keep getting worse for Sunderland boss David Moyes after he appears to have land himself in trouble with the FA, according to the Daily Star.

Moyes was believed to be involved in a tunnel bust-up with referee Bobby Madley following his side's last-minute loss to West Ham United on the weekend.

The Black Cats manager argued that Winston Reid's winning goal shouldn't have stood as at least one West Ham player was standing in an offside position.

Madley will now decide whether or not to include the incident in his match report before the FA makes a call on any punishment.

Moyes' side are currently rooted at the bottom of the league table, without a win this season and five points off safety.
