Chelsea manager Jose Mourinho has reportedly earmarked Atletico Madrid trio Koke, Diego Godin and Antoine Greizmann as his top three targets this summer.
The Blues, who recruited Filipe Luis and Diego Costa from the reigning Spanish champions last year, are looking to strengthen all over the field ahead of next season.
A report carried in The Metro claims that the triple swoop will see Chelsea splash out a sum of £106.5m, with £46m-rated midfielder Koke, who is also said to be wanted to Manchester United, the most expensive of the Atletico trio.
It is thought that Luis could be sold back to the Rojiblancos as part of any deal, which will help the Premier League champs comply with Financial Fair Play rules.
