Chelsea and Manchester City are set to go head-to-head for the signature of Atletico Madrid playmaker Koke, by triggering his £48million buy-out-clause, according to the Express.
Reports in Spain suggest the Premier League super-powers have their sights set firmly on the 22-year-old, who was instrumental as Atletico claimed a shock La Liga title last season.
Manchester United and Liverpool have previously held an interest in the Spanish international, but neither can match the buy-out-clause in the way City and Chelsea can.
Real Madrid and Barcelona have also attempted to sign Koke in the past, with Atletico refusing to enter into negotiations with their La Liga rivals.
That has signalled to both sides that a bid of anything below the buy-out-clause will not be considered, however Koke would still need to agree personal terms.
Chelsea feel they may hold the edge in negotiations, given that three of Atletico’s title winning side are already plying their trade at Stamford Bridge.
Thibaut Courtois, Diego Costa and Felipe Luis all arrived at Stamford Bridge in the summer, and have contributed to the Blues winning nine out of their opening 11 league games to sit comfortably top of the Premier League table.
