Adam Johnson has voiced his frustration after having a goal wrongly ruled out for offside against West Bromwich Albion.
The game ended 0-0 at the Stadium of Light, with Johnson's finish ruled out in the first half.
"We heard at half time it was clearly onside. These things seem to happen in every game for every team," he said in the post-match press conference.
"The officials have got to get them right because it's costing us three points and the chance to move up the table. I think West Brom came for the point. If we'd got the first goal, they'd never have scored."
Sunderland are currently 16th in the Premier League, three points above the relegation zone.
