Spurs boss Harry Redknapp has warned Premiership teams Chelsea and Manchester United that placing any kind of bid for Spurs' Croatian playmaker Luka Modric will be waste of time for the clubs as Spurs will not let go of the player in January.

Although Modric, 26, earlier wanted to move to Stamford Bridge, he remained at White Hart Lane and has since played a big part in helping its current 11-match unbeaten run which has propelled them to third position in the Premier League.

Tottenham succeeded in holding on to Modric this summer although they received as many as three offers for the Croatian. The biggest offer was reported to be somewhere around £40 million.

However, latest reports suggest that the Blues will replenish their interest in the Croatian when the transfer window opens next month as they ready themselves for a final push towards the title. Manchester United, on the other hand, will know that Modric's inclusion will provide with the edge that they currently lack in the midfield area.

Redknapp, nonetheless, has hinted that he could be letting a couple of fringe players go when the window opens. This revelation may fuel speculation over the future of the likes of Russian striker Roman Pavlyuchenko, Brazilian goalkeeper Heurelho Gomes and Cameroonian defender Sebastien Bassong. All the three players were previously reported wanting to leave to get more play time elsewhere.

The Spurs are also considering bids for Bolton's Gary Cahill and Chelsea's exit-bound striker Nicolas Anelka and the Spurs boss said that these players were a good acquisition for any team. However, the team is not known to have made any enquiries about Chelsea's out going defender Alex.

Redknapp later added that the decision to hold on to Modric has been taken by both him and chairman Daniel Levy, according to a Mirror Football report.

Luka Modric, who arrived from Croatian football club Dinamo Zagreb in 2008 for a total fee of £16.5 million, has made 132 appearances for the Spurs.
