Harry Kane's eighth goal in six Premier League games against Southampton steered 10-man Tottenham Hotspur to an unlikely 2-1 victory after errors from his teammates on Saturday.
Kane scored with a low shot from inside the area in the 43rd minute to restore Spurs' lead at the Tottenham Hotspur stadium after keeper Hugo Lloris had gifted Southampton an equaliser.
The Frenchman took far too long to clear a backpass and then wildly miskicked to allow the onrushing Danny Ings to bundle the ball over the line and cancel out Tanguy Ndombele's 24th-minute Spurs opener.
With Nathan Redmond also shooting over the bar and Ings failing to get on the end of a close-range chance, Southampton continued to put pressure on Spurs but the London side, who moved into fourth, remained dangerous on the break and Kane almost grabbed his second goal late on.
The win was only Spurs' second in eight games and moved them joint fourth, 10 points adrift of leaders Liverpool.
Lloris was relieved his mistake did not cost his side the points.
"I was really upset with myself, but I think it's more about how you respond and I'm really pleased with my performance in the second half," he said.
"As a keeper, sometimes you are faced with these type of situations. You just need to stay clam and stay focused. It is more about how you respond to that kind of mistake."
Spurs manager Mauricio Pochettino accepted the blame for Lloris's mistake,
"I demand that he plays in this way," he said.
Pochettino, who has spoken of the problems in his squad this season, said he was delighted with their spirit in battling for more than an hour with 10 men.
"I am really proud, and happy for the players and fans. They deserve a victory like this," he said.
"We needed to work a lot, to stay together and it showed our spirit."
Pochettino said he thought both cards given to Aurier were "completely unfair" but said he did not want to complain.
Spurs are next in action on Tuesday, when they host Bayern Munich in the Champions League.
