Swansea's Carlos Carvalhal received apology over Tottenham goal after 2-0 defeat
Swansea boss Carlos Carvalhal revealed assistant referee Marc Perry apologised to him for not ruling out Tottenham's first goal in his side's 2-0 defeat.
Fernando Llorente's first Spurs goal and Dele Alli's late settler secured victory - their fifth in six Premier League games - and took them above neighbours Arsenal.
But the victory was mired in controversy as Llorente - who started with Harry Kane kept on the bench until the last quarter because of a cold - was standing in an offside position when he nodded home Christian Eriksen's 12th-minute free-kick.
And Davinson Sanchez was fortunate not to be sent off 10 minutes after half-time for scything down Martin Olsson when he had already been booked.
"I've arrived in the Premier League and I will not start talking about referees," said Carvalhal, the former Sheffield Wednesday boss who had began his Swansea reign with a 2-1 win at Watford on Saturday.
"There are two points I can talk about. One, the linesman (Perry) apologised at the end of the game.
"I understand it's a mistake. I make mistakes, all of us make mistakes. It's OK.
"Second point, Pochettino is a clever manager because he substituted Sanchez in that moment.
"He's clever, he knows why he substituted him. After this I don't want to talk about nothing."
Swansea remain bottom of the table and four points from safety with 16 games left to play.
Spurs boss Mauricio Pochettino a dmitted his side got lucky as they moved to within four points of fourth-placed Liverpool with a game in hand.
"Always in football you need some luck to open the games up," Pochettino said.
"It's true that Swansea can maybe complain and it's right to complain, but in football this can happen.
"I didn't see the goal - people say it was offside, maybe.
"But I am pleased for Fernando because it was important for him to be involved and a striker always needs a goal."
The game was played in appalling conditions as Storm Eleanor made its way to south Wales.
But there was another storm brewing when referee Bobby Madley allowed Sanchez to escape with a lecture for felling Olsson rather than brandish a second yellow card.
"We were all worried about the second yellow card," said Pochettino, who substituted Sanchez four minutes later and sent on Victor Wanyama for his first action since August.
"The first half yellow card wasn't bad, but the fans started putting pressure on the referee and it can become a problem.
"So I decided to take him off the pitch - but I felt we deserved the victory."
