Newcastle manager Kevin Keegan says midfielder Charles N'Zogbia may leave the club at the end of the season.

The 21-year-old signed a five-year deal at St James' Park in September but was linked with a move to Tottenham in the January transfer window.

"Charles came to talk to me about speculation that there was interest from Spurs," Keegan is reported to have told French newspaper L'Equipe.

"We'll look at it in the summer as the signs are he is not happy here."

N'Zogbia has started every match of Keegan's tenure at the club, but he has often found himself at left-back instead of his favoured position in midfield.

The Frenchman, who joined from Le Havre for £250,000 in 2004, is believed to favour a move to London as that is where his mother and his sister live.
