Atletico Madrid are hoping to bring Chelsea duo Juan Mata and Kevin De Bruyne to Spain as they prepare to let Manchester United and Liverpool target Koke leave in the January transfer window. Both Mata and De Bruyne have seen first-team action under Jose Mourinho limited since he returned to the club as manager in the summer. De Bruyne has endured a frustrating time at Chelsea and is yet to complete a full 90 minutes for the club since making the move from Belgian side Genk in 2012. Despite Mourinho indicating the Belgian international would be in his plans for the season, regular playing time has not been forthcoming. Mata has also seen his chances restricted with varied combinations of Eden Hazard, Oscar, Willian and Andre Schurrle preferred in the attacking positions behind a lone striker. With Mata, 25, and De Bruyne, 22, looking to secure their places in the Spanish and Belgian national squads for next summer's World Cup limited opportunities at Stamford Bridge are becoming a major concern for both. According to reports in Spain, Atletico boss Diego Simeone is desperate to ensure he has adequate replacements for the expected departure of star man Koke in the new year and has earmarked Mata and De Bruyne. StarSport reported last week that De Bruyne held a meeting with Atletico representatives after Mourinho gave him his blessing to leave the club. Simeone is now hoping to conclude a double deal to bring Mata and De Bruyne to the Vicente Calderon Stadium. The Atletico boss' urgency to secure a deal comes with United ready to activate Koke's £16m release clause which is inserted into his current contract.
