Chelsea are leading Manchester United and Manchester City in the race to sign Atletico Madrid midfielder Koke this summer, and are prepared to pay £40 million to bring the Spaniard to Stamford Bridge.
According to The Sun on Sunday, Blues boss Jose Mourinho is in pole position to secure the 23-year-old's signature as he looks to strengthen his title winning squad ahead of another tilt at the domestic trophy next season.
Koke has attracted widespread interest following his rise to prominence at the Vicente Calderon, but it's Chelsea that appears the most likely destination when the transfer window reopens.
Louis van Gaal and Manuel Pellegrini have both been mooted as admirers of the Spain international too, but there hopes of luring him to Old Trafford or the Etihad Stadium look set to be crushed by the Blues as they prepare a big-money move.
Koke has been a virtual ever-present in Diego Simeone's side ever since making his senior debut six years ago. However, his future could lie away from La Liga amid rumours he'll move to the Premier League in time for the start of the 2015/16 campaign.
After signing Diego Costa and Filipe Luis from Atletico last summer, Chelsea have a good relationship with the Spanish club, and could even allow the Brazilian left-back to rejoin his former employers as part of the Koke deal.
His arrival in west London would allow Cesc Fabregas to push further up the pitch, with the youngster set to partner Nemanja Matic in Mourinho's midfield engine room.
