Chelsea have been given a clear indication from that they will have to up their offer to bring Willian to Stamford Bridge.
Shakhtar Donetsk confirmed earlier in the week that the Blues had tabled an offer for the talented 23-year-old, with Sergei Palkin claiming a €20 million bid was turned down and that the player wasn't for sale.
And the club's assistant manager Alexandru Spiridon has waded into the debate, claiming the Brazilian is of a similar ilk to Eden Hazard, if not better than the Belgian in some areas, and that their bid would have to be raised to secure Willian's services.
"I think the transfer fee offered by Chelsea does not match Willian’s skill. You probably know from the internet that Eden Hazard’s transfer value is £30m. Chelsea offered £16.5m for Willian.
"I do not think that Willian is weaker than Hazard, and in some components he is even stronger."
The former Corinthians starlet has a €35 million release clause in his contract at the Donbass Arena, although Palkin did hint at the time of the first offer that Shakhtar could consider an offer below the buy-out fee.
Were Andre Villas-Boas to secure Willian's services this month, he'd join Gary Cahill as a January addition in west London. Kevin de Bruyne could also be an addition, if Racing Genk's comments are to be believed.
