Southampton and Aston Villa scored late winners in matches affecting opposite ends of the Premier League on Tuesday, while a touchline spat between the managers marred Sunderland's 1-1 draw at Hull.
Southampton revived its unlikely tilt at Champions League qualification thanks to Sadio Mane's 83rd-minute goal in a 1-0 home victory over Crystal Palace. The south-coast club jumped provisionally to fifth, a point behind Manchester United.
Villa climbed out of the relegation zone — at least for a day — thanks to a 2-1 win over West Bromwich Albion that was secured by a penalty converted by Christian Benteke in the fourth minute of injury time.
Sunderland manager Gus Poyet was sent to the stands before squaring up to Hull counterpart Steve Bruce in a feisty match at KC Stadium.
