Shakhtar Donetsk midfielder Douglas Costa has said that he still dreams of playing for Chelsea one day despite a move in January failing to materialize.

There was plenty of speculation during the winter transfer window that the 24-year-old was a target of Chelsea boss Jose Mourinho and that the deal fell through because the Ukrainian side were demanding £30 million to let him leave.

When speaking to Four-Four-Two the Brazilian said: ‘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.’

‘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.’

He added: ‘There comes a time when you become sick and tired of playing in the same league. I’m 24 and I think that it’s worth trying to convince them to let me go away.’
