Manchester United boss Ole Gunnar Solskjaer: "It's very embarrassing, it hurt all the players. It hurts me as the manager. It's my worst day ever.
"I'll hold my hands up, I'm responsible for this. I've lost 5-0 with United and we've lost 6-1. We've lost big results before and always bounced back.
"I promise we'll do everything we can to turn this around. We know how good they can be but today all our mistakes came almost like Christmas everything at once and if you make too many mistakes against a good team and you'll be punished."
Tottenham boss Jose Mourinho: "To win 6-1 against Manchester United at Old Trafford is an honour for all of us, considering the dimension of Manchester United and Old Trafford.
"The pleasure is not the 6-1, the pleasure is the performance and three points which we really need after losing points at home against Newcastle.
"The target, objective is every match we go to win. I told the players in the last couple of days 1000 times a good result at Old Trafford is to win.
"Of course if you draw it's not a bad result but that's the kind of mentality we must get. It was a great performance, a great result. We have seven points, so our position in the table is so-so."
