Brazil international Willian, a reported target for both Chelsea and Tottenham, is becoming increasingly troubled at Shakhtar Donetsk after failing to return for the club's winter training camp.

According to the Evening Standard, Willian is being pursued by Chelsea and Tottenham during the January transfer window, and he is now at loggerheads with his current employers.

The 24-year-old has reportedly been outlined as a top target for Spurs manager Andre Villas-Boas, although Chelsea could contest the Portuguese in his bid to bring the midfielder to White Hart Lane.

Willian impressed against Chelsea during the Champions League group stages against the Blues - scoring twice at Stamford Bridge - to display his credentials to the west London club.

With reported interest from Chelsea and Spurs perhaps clouding his judgement, Willian has upset Shakhtar be failing to report for club duty after a trip to Brazil, and manager Mircea Lucescu believes the player is trying to force a move.

“It is not very nice to say that Willian did not return from holiday on time and thus he is exerting a certain pressure on the club,” said Lucescu, as reported by the Evening Standard. “I think it was unprofessional of him.

“The president decided to do everything possible to sign a player of Willian’s level, who already has experience of playing at a high standard. We look forward to having Willian again and I would like him to come back and behave as he did before – as a professional and decent man.

“I would like him to solve his problems in a civilised manner here in Donetsk, and not by phone. I have great respect for Willian and I would not like him to be put under pressure by the people who surround him, and who perhaps advise him the wrong things.

“He should reject the advice of those who surround him – they are not doing very good things. With or without Willian, Shakhtar will move on.”
