Tottenham Hotspur boss Mauricio Pochettino has insisted that he is not concerned by star striker Harry Kane's goal drought.

Kane, 21, became the first Spurs player since Gary Lineker to reach the 30-goal barrier in a season but he has not found the net in the four games since.

"This happens in football, up and down with a player, and all sometimes the period during the season it is difficult to score every game," he told a press conference.

"But I am not worried about that and only now we need to back him and be positive in the future."

Spurs finish their season with a visit to Everton on Sunday afternoon.
