Leeds defender Tom Lees has signed a new four-year contract with the npower Championship club.
He quickly established himself as a first-team regular at Elland Road, making 44 appearances and making a big impression on manager Neil Warnock.
The United boss told the club's official website: "Tom was probably the one bright spark at the back. He's improved his all-round game to such an extent that he was one of the first names on the team-sheet.
"There will be plenty of competition at the back next season because I am looking to bring in defenders. But he has every attribute.
"Tom's a great lad, he's Leeds through and through and I see him having a great career here."
