Chelsea manager Jose Mourinho has all but confirmed the Blues will sign a left-back to replace Filipe Luis before the end of the transfer window but was coy on reports linking them with Everton starlet John Stones.

The Portuguese manager has been relatively quiet during the current transfer window after winning both the Premier League and the League Cup during the 2014-15 campaign.

The Blues have only signed two major names in Radamel Falcao and Asmir Begovic to fill the void left by the departures of Didier Drogba and Petr Cech. They have also confirmed moves for young duo Nathan and Danilo Pantic, with Brazilian starlet Kenedy expected to join them should he secure a work permit.

But the Premier League champions have been heavily linked with both a left-back and John Stones in recent days as, following Luis's return to Atletico Madrid, Mourinho only has five established first-team defenders in his ranks: Cesar Azpilicueta, Branislav Ivanovic, John Terry, Gary Cahill and Kurt Zouma.

He has confirmed the Blues are expected to sign a new left-back before the end of the transfer window. "We have only one, we are trying [to sign another one]," Mourinho admitted during the press conference ahead of the Community Shield game against Arsenal on 2 July.

Augsburg defender Abdul Baba Rahman has been heavily linked with a move to Stamford Bridge during the summer, while the Daily Mail claimed the club have also contacted Galatasaray about Brazilian left-back Alex Telles as he would be cheaper.

Meanwhile, Mourinho was coy on links with Stones after the Telegraph reported the Blues are planning to make an improved third offer for the defender after having had a £26m bid turned down by Roberto Martinez's side earlier in July.

But asked about the interest in the defender, he said: "I don't speak about players from other clubs, especially now [the] competition starts. It starts for us and Arsenal now, and next week for everyone."
