An own goal by Michael Keane was enough to give Tottenham Hotspur their second win in three matches, as they beat Everton 1-0.
Defeat would have seen Spurs fall below the visitors into the bottom half of the table but they held on fairly comfortably to stretch their unbeaten league run versus Everton to 15 games.
The Toffees defender had no chance of getting out of the way as Giovani Lo Celso's shot deflected off him and past the helpless Jordan Pickford in the 24th minute.
Son Heung-min came close to doubling the lead early in the second half but sent a shot wide and was also twice denied by Pickford.
Everton couldn't find a leveller as Dominic Calvert-Lewin's late header was saved by Hugo Lloris and Djibril Sidibe drove wide in stoppage time.
Midfielder Giovani Lo Celso thought he had scored his first Premier League goal for Tottenham in the 23rd minute but his shot on the turn took a decisive deflection off Keane to leave keeper Jordan Pickford with no chance.
Spurs keeper Hugo Lloris was hardly tested in the first half although he was involved in a flashpoint as the players left the pitch at the interval, getting into a furious row with team mate Son Heung-min.
Son forced a couple of saves from Pickford in the second half while Everton offered precious little as they lost their first game since the resumption of the season.
Tottenham have 48 points from 33 games, one behind Arsenal and nine adrift of fourth-placed Chelsea. Everton remain 11th.

Tottenham: When Tottenham captain Hugo Lloris confronted Son Heung-min on the field at halftime, Jose Mourinho was far from annoyed.
The manager renowned for his own flashpoints and volatility was delighted to see tensions between teammates erupting in public view.
"It was beautiful," he said. "Probably it's a consequence of our meetings." Angered by the timidity of a 3-1 loss at Sheffield United in the previous English Premier League round, Mourinho saw the passion he wanted as Tottenham this time secured a 1-0 victory over Everton on Monday.
Just before the break, with Tottenham leading, Son lost the ball which led to Richarlison having a chance to equalise but striking wide of Lloris' post.
"I think to concede a chance a few seconds before halftime because we don't make the pressing properly," Lloris said, "that annoys me but it's part of football. Move on."
Only, Lloris didn't when the whistle blew for halftime, shouting as he raced over to Son. Giovani Lo Celso and Harry Winks intervened to split the clashing teammates before they headed into the dressing room.
Son had created the goal in the 24th minute. The South Korea forward knocked the ball forward to Harry Kane who squared for Lo Celso to strike on the turn and Everton defender Michael Keane deflected the ball into his own net.
"An amazing kid that everyone loves like Sonny, a team boy," Mourinho said.
"But in that situation the captain thought the last minute of the first half you have to do more for the team. You have to give a different effort than you give. A couple of bad words but I think it's something very important for the team to grow up."
In the dressing room, Mourinho told them: "I have no doubt you will stick together until the end." That they did. Tottenham moved up to eighth place with its second victory from the four games since the league resumed after a three-month suspension.
But it's not only the hopes of returning to the Champions League that are in the balance for Spurs. Even qualifying for the Europa League is uncertain with five games remaining.
"If you want to blame someone for that it is me," Mourinho said.
"I was critical of my boys because they are not enough critical of themselves (in Sheffield) ... I ask them to demand more from each other. That pressure to give for everyone."
Mourinho was hired in November to rescue the season after Mauricio Pochettino was fired with a team that reached the 2019 Champions League final in 14th place.
"When you play a season like this one it is very easy to fall apart as a team," Mourinho said.
"Today we showed we are still together and ready to compete and ready to fight until the end."
At the end of the game, Lloris and Son embraced on the pitch - despite the need for social distancing to be maintained due to the coronavirus pandemic which means no fans are allowed into games.
"What happened between me and Sonny is just something that is part of football sometimes," Lloris said.
"But there is no problem at all. You can see at the end of the game we are more than happy to be part of the team and to have these three points."
