The West London side are also tracking Brazilian attacker Willian, who had previously been linked with a move to join the Blues before completing a £30m switch to Anzhi.
The 24 year old could now apparently be available for a lot less and Mourinho may well feel that the playmaker could offer a further direct attacking dimension to his Chelsea side.
The winger could well be tempted by the chance to join national team colleagues David Luiz, Ramires and Oscar at Stamford Bridge. Willian hasn’t impressed since moving to Anzhi, netting just one goal in 15 matches and the opportunity to re-ignite his career in the Premier League could be tempting and if a decent fee is offered then Anzhi may well elect to sell the former Shakhtar Donetsk man.
