Tottenham Hotspur boss Mauricio Pochettino has backed 'world-class' striker Harry Kane to hit the goal trail for the London club over the festive period.

Kane netted an impressive 25 Premier League goals during the 2015-16 campaign, but he is only on seven this season and has not netted in his last three appearances for the club.

Pochettino, however, has said that he has 'no worries' about the form of the 23-year-old ahead of Spurs' visit to Southampton in the Premier League on December 28.

"I am not worried about him. For me he is one of the best strikers in the world, for different reasons maybe he didn't score in the last few games, but I have no doubt that it is only a few games. He is a fantastic player and a top scorer. I have no doubt he will start to score as soon as possible," Pochettino told reporters.

Kane's best scoring season for Spurs to date came in the 2014-15 campaign, when the England international managed 31 goals in 51 appearances in all competitions.
