Stoke City piled the pressure on Louis van Gaal with a 2-0 victory over Manchester United at the Britannia Stadium.
United -- who started with captain Wayne Rooney on the bench -- had an early chance when Jack Butland struggled to control a backpass and Memphis Depay nearly took advantage, but the goalkeeper recovered.
Stoke found themselves in the lead on 19 minutes when Glen Johnson set up Bojan Krkic to slot home at close range following a poor header from Depay towards David De Gea.
They doubled their advantage soon afterwards when the ball fell to Marko Arnautovic on the edge of the area following a free kick and he fired a powerful shot beyond De Gea's reach. It might have been 3-0 soon afterwards, but Arnautovic fired wide with only the keeper to beat.
Rooney was brought on for Depay at the break, and he nearly helped United find a way back into the game when he set up Marouane Fellaini in front of goal with just over an hour gone, but the Belgian's shot was tame and Butland made the stop.
