The 21 year old’s impressive form this season, including a hat-trick against Italian giants Inter Milan in the Champions League, has attracted interest from across Europe.
Hailed as “one of the top left-sided players in the world” by manager Harry Redknapp, the Spurs boss is delighted the Welsh international has pledged his future to the club.
Redknapp said: “It’s great to have Gareth sign a new contract at the club.”
“He really is an amazing talent and can only get better. He is a smashing lad as well, which is equally as important.”
“He has got his whole future ahead and he has everything going for him.”
