Despite going a goal ahead early on through a Bruno Fernandes penalty, a long line of errors and relentlessly atrocious defending saw United conspire to lose 6-1.
Spurs managed to equalise and take the lead with just seven minutes gone and, when Anthony Martial was sent off following an off-the-ball incident involving Erik Lamela, things went downhill quickly.
After Martial’s dismissal Son Heung-min and Harry Kane scored to make it 4-1 at the break before two more goals were added in the second half.
Shaw took responsibility for the defeat on behalf of his teammates and admitted that they are performing nowhere near the level they should be at the moment.
“I think who ever’s on the pitch, whenever you’re on the pitch, whatever the scoreline is, the players on that pitch have to take responsibility,” he told Sky Sports after the game.
“We get given tactics before the game, responsibilities that players need to do, but I think when you’re on the pitch the manager can only give advice and what he thinks but we’re the players that are on the pitch and we need to have very high standards.
“The players we have here have that quality but I think it hasn’t been showing. We have to look ourselves in the mirror as individuals but as a team collectively we’re no where near it at the moment.”
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.”
