Leeds United defender Tom Lees has penned a new long-term contract at Elland Road.
The versatile 20-year-old, who can play in both the centre back and right back positions, has made seven appearances for the Whites since debuting in August, and has become an integral part of Simon Grayson's squad.
"It's been tough and I've been learning lots, but I've enjoyed playing regularly and being a part of the team," he told the official Leeds United website.
"It's been a step up for me and it's a good challenge."
Lees has spent large spells on loan with both Accrington Stanley and Bury in the past two seasons, earning more than 100 appearances in the Football League and Cup competitions.
His aim now is to become a regular in the Leeds United side, and the youngster just wants to continue developing at the club.
"I wouldn't have thought I would be in this position now, but I know my future is here and my aim is to keep improving, keep learning, and keep getting better."
Lees' deal will see him stay at Leeds United until 2015.
