Chelsea: Shakhtar Donetsk star Douglas Costa still wants 'dream move' to play under Jose Mourinho

Shakhtar Donetsk midfielder Douglas Costa is desperate for his chance to play in the Premier League and believes he can achieve anything he wants working alongside Jose Mourinho at Chelsea.

Costa, 24, confirmed in January that the Blues were interested in signing him but the club eventually opted to sign Juan Cuadrado from Fiorentina.

But while Chelsea decided to move in a different direction, the Brazilian midfielder is still hopeful of a move to west London where he believes Mourinho's philosophy of the game will allow him to thrive.

"I'd be really interested in moving to Chelsea – not only because 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."

But Costa believes his price tag could complicate any potential transfer. Chelsea learned all about Shakhtar's hard-ball tactics in the transfer market when they were forced to meet Willian's €35m (£25m, $37m) release clause in the summer of 2013. With Costa's clause at €50m, he is aware getting his dream move won't be easy.

"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."

Mourinho welcomed Costa's interest in moving to Chelsea during the January transfer window but it is not yet known whether the west London club will rekindle their interest in the midfielder during the summer.
