Shakhtar Donetsk manager Mircea Lucescu believes that Chelsea should have met his clubs asking price for Willian.
The Blues were in negotiations with the Ukrainian outfit for the Brazilian playmaker this summer but did not cough up a reported £27million for his services.
Lucescu sees day in-day out what Willian is capable of and he has suggested that Chelsea made a mistake in not offering more for the 24-year old.
"Willian was far away from Chelsea," said Lucescu ahead of Shakhtar's Champions League clash with the Blues tomorrow night.
"They didn't even get anywhere near to our requirements, having done nothing to make my promises to Willian come true.
"Speaking specifically about the amounts, they officially offered the sum for which we had bought him young.
"I would really like them to highly appreciate his true value tomorrow and realise that they made a big mistake."
