A Jan Vertonghen goal on 75 minutes was enough to give the hosts at White Hart Lane a 1-0 win, and although the Dane had no qualms about the result, he was unhappy that play was not halted after the Spanish forward fell to the ground after a collision with Spurs goalkeeper Hugo Lloris.

"I was very angry," Laudrup said.

"It wasn't because I wanted a free-kick, red card or penalty.

"When things happen like possible head injuries, you have all the linesman and the referee who can see it. The referee and linesmen were watching Michu on the ground and still didn't stop the game. It was so poor, it was dangerous. I would like an explanation.

"I just wanted the game stopped in that moment because it was a head injury. He was on the floor looking unconscious; you can't fake something like that."

Since their last visit to north London, when they defeated Arsenal 2-0 at the Emirates Stadium, Swansea have not won in the Premier League, suffering a 4-3 loss at home to Norwich, and the defeat on Sunday against Spurs.

Yet Laudrup said he was happy with the Swans' performance at White Hart Lane, and the desire and effort put in by his players.

"I think we started quite well and what we expected happened," he added.

"We were put under pressure, and they played really well for 15-20 minutes.

"Nil-nil after the first half was a great result for us. We had two or three chances, second half I think they still had the ball but didn't look dangerous, (so) conceding a goal like that was a little disappointing.

"Maybe our passing game wasn't at its best but we were still so competitive against a very good team at their ground. I can't complain about the result.

"We tried our best and that's important for me."

Tottenham manager Andre Villas-Boas was relieved his side managed to avoid their habit of conceding late goals, as they absorbed some late pressure from their Welsh visitors.

Spurs have conceded 10 goals in the final 15 minutes of league games this season - including two in the defeat at Everton last weekend - but held on to nab all three points on Sunday.

Villas-Boas admitted the team have been working on their concentration in training during the week and is now targeting a push towards the top two ahead of the busy festive fixture period.

"Yeah I was a bit nervous," said Villas Boas.

"Football is unpredictable but today the players showed the desire and ambition to put right the wrongs.

"We addressed it in training as a group, concentrating in the last part of training. It's difficult because you can't recreate the stressful environment of a game. We had a go, we made the exercises more complex and made the players think with the tasks that they have to do.

"Today doesn't mean the problem is solved but we are working on it.

"For us, it's important to break out of this pack, but that's difficult to do. It's not easy but we want to distance ourselves.

"The problem is that the Premier League this season is very tight from third to 10th. Teams are separated by four or five points."
