Shakhtar Donetsk playmaker Willian is still hoping to secure a move to Chelsea, despite fellow Brazilian Oscar being close to completing a move to Stamford Bridge.
Internacional attacker Oscar has confirmed he has had a medical with Chelsea - but will not make a decision on whether to join the Blues until after the London 2012 Olympics.
Shakhtar president Rinat Akhmetov this week said Chelsea can sign Willian, who has been on their radar since last summer, providing they pay €30million.
And the 23-year-old is unhappy that his club appear to be increasing his asking price.
"I don't know what the coach said, but the correct value is €25m," Willian told Globo Esporte.
"Regardless of the price, it is clear that the desire is great to play at a club like Chelsea, the champion of the Champions League.
"I'm really upset with the board for not letting me leave. It would be good for me and also for the club. I'd be in a big city and have the chance to grow professionally. This is not a message to anyone, everyone knows I want to leave."
Although Chelsea and Internacional are believed to have agreed a fee in the region of £30million for Oscar, Willian believes they could both play in the same team.
"I'm sure it will not matter, because the way we play is different," he continued.
"It is a matter of waiting. The hope is the last to die and a lot can happen there."
Willian added that he would look forward to the prospect of facing former club Corinthians at the Club World Cup in December should he secure a move to west London.
"It would be an extra special moment for me," he said.
"I was raised in Corinthians and to be there in the shirt of Chelsea, one of the biggest clubs in the world, would be priceless.
"I was with David Luiz and Ramires in the Selecao. If this actually happens, it will be great."
