Tottenham boss Harry Redknapp is waiting for developments in his efforts to sign former Arsenal midfielder Patrick Vieira from Inter Milan.

Redknapp's priority at the moment is for cover at centre-back but he is also in the market for a defensive midfielder and the club have made an enquiry to Real Madrid about Lassana Diarra.

"Patrick was someone I was interested in but I'm not sure where that's gone. It's not developed," Redknapp said.

Vieira's wages are thought to be the main obstacle if a move is to be agreed and it would also be a controversial signing after the 33-year-old spent nine years at rivals Arsenal.

Regarding his interest in Diarra, whom Redknapp signed for Portsmouth from Arsenal, the Spurs boss added: "We spoke to Real Madrid and made an enquiry but there was nothing doing."

Redknapp has signed Kyle Naughton and Kyle Walker from Sheffield United already this summer, while Didier Zokora has left for Sevilla.

Redknapp has played down suggestions David Beckham could arrive on loan from Los Angeles Galaxy.

He told dailymail.co.uk: "David's a great player and a great professional but we have players in that position so nothing will happen there."

Brazilian defender Gilberto, meanwhile, has left Spurs after his contract with the club was cancelled by mutual consent.
