Tottenham boss Mauricio Pochettino hailed matchwinner Christian Eriksen after victory over Sunderland.

Jan Vertonghen's deflected shot gave the hosts a third-minute lead, but the visitors equalised through Sebastian Larsson's superb free-kick, won by former Spurs man Jermain Defoe on his Black Cats debut.

Larsson's strike looked to have earned the Black Cats a valuable point, but Eriksen added a late twist when his placed shot from edge of the area went in off a post with two minutes remaining.

It was the 22-year-old's eighth goal in the Barclays Premier League this season.

"I am happy for Christian," Pochettino said.

"He is still young, but he has big, big potential. He improves every day. I am happy for his performance.

"His contribution is clear. I am happy because he is a very good guy, a good professional and a great player."
