Chelsea have reportedly asked Tottenham Hotspur to name their price for left-back Danny Rose, according to the Mirror.
Jose Mourinho has already confirmed that the Blues are in the market for a left-back to replace Felipe Luis, who returned to Atletico Madrid after just one season at Stamford Bridge.
"We are trying to sign a left-back. We have only one [César Azpilicueta]. We are trying," the Portuguese manager said, as quoted by the Guardian.
The Premier League champions have been heavily linked with a move for Augsburg full back Baba Rahman, with The Guardian reporting that Chelsea are close to completing the deal. Even the player's agent Sascha Empacher confirmed talks between the two clubs to take the Ghana international to west London.
"Both clubs are still working on fine-tuning but we hope the agreement will be finalised soon," the Ghana international's agent told Guardian Sport.
The report claims that Chelsea are keen on signing Rose, who is a regular in the Spurs first-team, and it is suggested that the Stamford Bridge outfit are willing to pay a fee of around £15m to sign the English defender.
Mauricio Pochettino will be reluctant to let his first choice defender leave the club, especially after christening him one of the best left-back's in England last season.
However, the report claimed that due to the presence of Welsh international Ben Davies in the squad, the north London club could be willing to let the player leave for the right offer.
Chelsea are said to have made their approach this weekend and are now waiting for Tottenham to quote a price, but the Blues will move for Rahman if a price cannot be agreed with the White Hart Lane outfit.
