"We were not good enough to stop the counter-attack".
United, who kicked off eight points behind leaders Liverpool, already look out of the Premier League title race and a rift between the manager and Paul Pogba is overshadowing events on the pitch. He's there to put a team out and put a team out that he thinks can win the game.
Speculation regarding a possible move for the World Cup-winning midfielder continues to build, with a breakdown in his working relationship with Jose Mourinho edging him ever closer to the exits.
When asked by BT Sport whether he had a message for Mourinho, the Austria global replied: "No, nothing to say".
United, who went two down before halftime with a Victor Lindelof own goal, offered a little resistance with a second-half goal from Marcus Rashford only for their central defence to be sliced open once more nearly immediately as Marko Arnautovic struck the Hammers' third. It's hard to take and we're sorry to the fans for what they saw today.
"I just think they have actually become a very, very average team with a very negative manager".
The pressure on Mourinho is increasing after every matchday as the Portuguese tactician has seemingly run out of ideas to arrest a slide at United. "To play him as a second striker and trying just to cover the area of [Declan] Rice would be much easier for him and at the same time, I feel that we need quality on the ball building up from the back and Scott McTominay has that quality with the ball".
The Red Devils are nearly out of the top 10 and nine points off the top of the Premier League table. It was very poor from us. There was no coherent offensive strategy as they sleepwalked to a defeat that looked on the cards from the moment Felipe Anderson scored his maiden goal for the club.
