Manchester United were left clinging onto their top-five status in the Premier League after suffering a 2-1 defeat at Sunderland on Saturday, where an 82nd-minute David de Gea own goal ended the Red Devils' three-match unbeaten streak.
West Ham United now sit just a point behind Louis van Gaal's men after Dimitri Payet led their comeback to clinch a 2-2 draw at Norwich City, with Southampton also on the Red Devils' heels following their 1-0 win over Swansea City.
Elsewhere, Watford and Stoke City moved up to eighth and ninth, respectively, following wins over Crystal Palace and Bournemouth.
