Tottenham will test Chelsea's resolve to hang on to their fringe players by making a £6million move for England left-back Wayne Bridge.
Coach Martin Jol offloaded defender Noe Pamarot along with midfielders Sean Davis and Pedro Mendes to Portsmouth in a £7.5million deal and then refused to rule out making a move for the unsettled Bridge.
Chelsea coach Jose Mourinho has repeatedly insisted nobody will be leaving his Stamford Bridge squad unless they are unhappy and want to quit.
But that situation may change once Spurs make an official approach for Bridge who is desperate for first-team football ahead of this summer's World Cup finals in Germany.
England coach Sven-Goran Eriksson has told the former Southampton defender he needs to be playing regularly to stand any hope of being included in his squad for the tournament.
Bridge has yet to figure in the Barclays Premiership for Chelsea since recovering from the serious ankle fracture he sustained against Newcastle in the FA Cup quarter-final last season.
