And Ward-Prowse's stunner could have hammered the final nail in the coffin - check it out down below:

What next for Tottenham?

Spurs will have to keep their fingers crossed that upcoming games fall in their favour, specifically regarding Chelsea and United who have games in hand.

The latter's clash with Arsenal will be of particular interest to Mauricio Pochettino's men, while Chelsea can clamber back to third spot with two consecutive wins.

Pochettino reflected in his post-match press conference: "I am a little bit worried, this change too much from the first half to the second half is only one reason, it’s mental. It’s about complacency.

"It’s about arrogance in a bad way. You use the first half like an example, arrogance, playing with intention, focus, concentration, we matched them in everything and we were much better.

"In the second half it was arrogance in a bad way."

Pochettino will be looking for a response in the upcoming fixtures with Crystal Palace and Liverpool.
