Manchester United lost more ground in the battle for a place in next season's Champions League after a dramatic finale in a 1-1 draw at Brentford on Saturday, as Son Heung-min fired Tottenham to a 2-1 win over Luton.
Aston Villa remain in fourth after a 2-0 win over Wolves, three points ahead of Tottenham, but now enjoy an 11-point cushion over United, who were lucky to escape west London with a point.
Mason Mount's first goal for the Red Devils in the 96th minute looked set to snatch victory for Erik ten Hag's men despite being thoroughly outplayed.
However, Brentford hit back three minutes later through Kristoffer Ajer to register just their second point in seven games.
"We were winning in the end, maybe it wasn't deserved, but then you have to take the three points," said Ten Hag. "It is very disappointing to draw the game."
Spurs have now come from behind to win in four of their last five home games and needed another second-half turnaround after Tahith Chong's strike put Luton into a shock lead after just three minutes.
An Ange Postecoglou half-time substitution again made an impact for Tottenham as Brennan Johnson's cross was turned into his own net by Issa Kabore just six minutes after the Welsh international's introduction.
Son had missed a number of chances earlier in the game but finally got some fortune when his deflected effort trickled past Thomas Kaminski for his 15th goal of the season.
"Until the end I was getting frustrated but I wanted to stay calm as captain," said Son.
"We don't want it to always end like this, it could be nicer when we have it (won) earlier."
Tottenham's victory briefly took them into fourth, but Villa responded as goals from Moussa Diaby and Ezri Konsa gave them the bragging rights from a Midlands derby.
