Tottenham midfielder Dele Alli has agreed a new deal that will keep him under contract at White Hart Lane until 2021.
The England international was signed from MK Dons on a five-and-a-half-year deal in February last year but has extended his deal by a further season after impressing for Spurs in his first Premier League campaign.
"I'm delighted. The club has been really great to me since I arrived," Alli told the club's official website.
"We've a great young team and I can only see us going forward. I'm really happy to be here.
"I can't say it's been easy but there's a great bunch of boys here who have helped me settle in as well as all the staff.
"They've all helped me and made it easy for me to go out there and do my stuff. That's massive, it helps with your confidence and helps you focus on your football.
"That's important, especially when you're a young player. I was confident in my ability when I moved up here, people talked about loans but when I signed here I wanted to play for Tottenham.
"I wasn't thinking about anywhere else at the time. Thankfully I've broken in, had a few games and established myself as a Premier League player.
"I'm 19, I've still got a lot to learn but I can't think of anywhere better to do that. The football [at Spurs] really fits me as a player."
The 19-year-old has made 26 appearances for Mauricio Pochettino's side in all competitions this term - scoring five goals - to help bolster hopes of a top-four finish for Spurs.
With Spurs also in the running for FA Cup and Europa League success, Alli's impressive form has earned him four England caps, having scored his maiden international goal against France in November.
