Douglas Costa: I'm keen on Chelsea & Mourinho is the best around

Shakhtar Donetsk midfielder Douglas Costa has reiterated his desire to join Chelsea and believes Jose Mourinho is currently the best manager in the world.

The 24-year-old revealed that Chelsea had been in contact over a potential move before the club signed Juan Cuadrado from Fiorentina.

But ahead of the summer transfer window, Costa admits he is keen to leave the Ukrainian champions and insists Stamford Bridge is his preferred destination.

"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."
