Chelsea are set to make a £22m bid for Atletico Madrid midfielder Koke, according to Daily Star.
According to various reports in the Spanish capital, Chelsea have their heart set on signing the impressive midfielder after watching his performances for at the Vicente Calderon this season.
The Spanish international has a £44m release clause in his contract with the Spanish champions but it is understood that Blues boss Jose Mourinho is confident he can agree a deal for half of that fee.
Koke, who has been at Atletico for 15-years, is happy to remain with Diego Simeone’s side but interest from Chelsea, who signed Filipe Luis and Diego Costa from the La Liga side last season; will test his loyalty to the club.
Manchester United and Manchester City are both interested with the latter keen to replace Englishman James Milner, who is out of contract this summer.
