Tottenham are in talks with Crystal Palace over the transfer of winger Wilfried Zaha, according to Sky sources.
Sky Sports News HQ understands Zaha has met with Palace manager Alan Pardew and told him he wants to leave.
Zaha made his name at Palace, breaking into the first team from their academy in 2010, and a fee for him to move to White Hart Lane is likely to be in the region of £15m.
In January 2013, Zaha left Palace for Manchester United for £10m, but remained on loan at the Eagles until the end of the season, helping them return to the Premier League.

He returned to Palace in August 2014 on a season-long loan, before rejoining the club on a permanent basis in February 2015. He made 43 appearances for the Eagles in all competitions last season, scoring five goals and contributing seven assists.
Spurs have been reportedly pursuing Marseille winger Georges-Kevin N'Koudou for much of the summer and have also been linked with a move for Bayer Leverkusen attacking midfielder Hakan Calhanoglu.
Speaking at a press conference ahead of Spurs' clash with Liverpool, live on Sky Sports 1HD on Saturday, Pochettino said: "I'm very happy with my squad. Whatever happens in the next few days is welcome.
"I hope we can add a good player to the squad to help us, I think it's another situation where we need to confirm whether we can add some players or not."
Palace brought in goalkeeper Steve Mandanda, defender James Tomkins and attacking midfielder Andros Townsend earlier this summer.
