In-form Newcastle United striker Demba Ba could be available for less than £7m, according to Tottenham Hotspur manager Harry Redknapp.

Ba, 26, has been in scintillating form this season, scoring 15 goals in 19 appearances for the Magpies, since joining on a free transfer from West Ham United in the summer.

The Senegal international's form has attracted interest from a host of top Premier League sides, with Tottenham believed to be weighing up an approach for the striker.

Newcastle boss Alan Pardew remains adamant the player will not be sold for less than £15m but it now appears the matter could be out of his hands.

Reports over the weekend suggested Ba's contract has a release clause which would allow him to leave for a fraction of his market value.

And Tottenham manager Redknapp revealed that clause could be significantly less than the £10m initially reported.

"I think you will find it is a lot less than that [£10m]," Redknapp said. "Even less than [£7m]."

But Redknapp refused to be drawn any further when questioned whether Tottenham were planning a bid for Ba, with Jermain Defoe and Roman Pavlyuchenko linked with moves away from White Hart Lane in January.

"The squad is fine," Redknapp said in the aftermath of Tottenham's 3-0 FA Cup victory at home to League Two side Cheltenham. "We're short at right-back. Corluka is not fit, he has been out for ten weeks and I don't know when he is going to be fit. Jake Livermore went there today and did a great job for us.

"As I've said all along if we bring someone in it will only be someone I feel can improve us rather than bringing a squad player in. we've got enough good players here.

"If we can find someone special than I am sure we would look to do something but other than that we won't bother."
