Brazilian starlet Douglas Costa, who is rated at €50 million, has expressed his desire to join Jose Mourinho at Chelsea.
The Shakhtar Donetsk winger joined the Ukraine side for just €8 million in 2010, but feels it’s time to take the next step in his career and join the world's best manager.
"I'd be really interested in moving to Chelsea – not only because of everything Willian tells me about the club, but because I think that I'd be able to achieve everything I want having someone like Jose Mourinho by my side," Costa told FourFourTwo.
"Since I left Brazil, I have worked with a marvellous coach (Mircea Lucescu) and got an idea of how much influence such a good professional can have in your football.
“Now I think it's time to try a new philosophy and I'm sure that Mourinho's is the best around. He's always fighting for trophies.
"Besides that, I'd have the chance to play in the Premier League, the best league in the world. What really impresses me is that you never know which team will win – that's a factor that always keeps athletes motivated."
Costa confirmed that the Blues were interested in his services in January, but he is afraid his massive €50 million release clause could block any potential deal.
"Willian had all that trouble and his release clause was €35m," Costa said.
"If you think that mine is even bigger, around €50m, you can imagine that it won't be any easier.
“I've also had talks with other sides like Milan and Monaco throughout this time, but none of them have reached the price asked by Shakhtar."
Costa featured in both Champions League Round of 16 games against Bayern Munich, but couldn't prevent Shakhtar from dropping out of the competition.
