Tottenham Hotspur striker Harry Kane has committed his long-term future to Spurs after agreeing a five-and-a-half-year deal at White Hart Lane, the north London club have confirmed.

The 21-year-old striker has been one of the club's top players during the first half of the season, even though he was initially behind Emmanuel Adebayor and Roberto Soldado in manager Mauricio Pochettino's pecking order.

Kane did not start a Premier League game until the 11th game of the season but has since proved to be a sensation, scoring 20 goals in all competitions including a brace against Chelsea on New Year's Day, as well a hat-trick against Tripolis in the Europa League.

Having netted a brace in the 3-0 victory over West Bromwich Albion on 31 January, Tottenham have confirmed a new deal for Kane as a reward for his clinical performances.

"The club is delighted to announce that Harry Kane has signed a new five-and-a-half-year contract, which runs until 2020," Spurs confirmed through the club's official website.

"The young striker, still only 21, has been in outstanding form for us this season with 20 goals in all competitions, including a memorable double against Premier League leaders Chelsea at the Lane on New Year's Day,"

"An Academy graduate, Harry made his first-team debut against Hearts in the Europa League in August 2011 and made his big breakthrough last season when he scored on his first Premier League start for us against Sunderland in April - the first of three goals in consecutive league games."

Meanwhile, the striker expressed his delight about the agreement on Twitter.

Kane signed a £15,000 per week deal with Spurs six months ago, while according to recent reports he is now set to earn around £35,000 per week.

The club recently secured the long-term future of Ryan Mason after confirming the midfielder had also signed a five-and-a-half-year deal at White Hart Lane.
