The Welsh winger has been the key man for Tottenham in their charge for the top four this season.
"It's a massive honour. To be voted by your peers is one of the biggest things in the game. It's great to win it and I am delighted," he said.
"When you look at the list, there are some massive names on it but I couldn't have done it without the team. They have been fantastic this year and so has the manager.
"The other nominees have been unbelievable, they have been outstanding for their clubs and it's a massive moment to win, especially as it's both awards and it's something that I'm extremely proud of.
"The biggest thing is playing for your team and going well. If you do well, then these awards come along. I have been shooting a lot more and I have been coming inside a lot more too. I have a few less assists this year but I am in more scoring positions these days and that has obviously helped my scoring tally as we have seen this season."
