Dele Alli put Tottenham's disappointing performance in Wednesday's 2-1 defeat to Manchester United down to arrogance borne out of the winning start they had made to Jose Mourinho's tenure.

Mourinho was appointed as Mauricio Pochettino's successor last month and had overseen three successive victories in his first three matches at the helm.

Wednesday brought Mourinho's first return to Old Trafford as a manager since he was sacked by the club in December 2018, but Spurs failed to continue their recent resurgence.

Marcus Rashford produced a talismanic display for the Red Devils, scoring both of their goals either side of a spectacular strike from Alli, who arguably more than anyone else has been re-energised by Mourinho's hiring.

But Alli's goal aside, Spurs created precious few clear-cut opportunities and were fortunate to be on level terms at half-time, with the former MK Dons talent suggesting Tottenham had begun to believe their own hype following three wins on the bounce.

"We had to match their [United's] energy. We lost the game not by them outplaying us – just attitude," the England international told reporters.

"We weren't hungry enough and we were slow to every second ball, losing 50-50s. Maybe it was a little bit of arrogance and over-confidence. We’ve been playing well.

"We have to learn from this. Games like this bring your feet back down."

Victory moved United up to sixth and provided manager Ole Gunnar Solskjaer a much-needed boost ahead of Saturday's Manchester derby at bitter rivals and champions Manchester City.

Spurs slipped down to eighth with the defeat.
