Shaw was perhaps fortunate not to see red himself after a scything tackle on Lucas Moura and he explained how much the result hurts.

"I think that lack of concentration and sloppiness and then a mistake, another mistake and even more mistakes that gave them chances and goals to come back into the game. The red card didn't help but I think even before then after the first goal we switched off.

"It really hurts. A club like Manchester United shouldn't be losing I don't think, but losing in this way and this sort of manner really hurts. It's kind of embarrassing because I feel we have let a lot of people down today who are watching at home. We let ourselves down, we let the staff down and it really hurts."
