Chelsea have been backed in to 1/3 favourites to sign Willian at the expense of Tottenham after Sky Bet re-opened betting on the Brazilian's future.
The online bookmaker suspended the market earlier this week as the Anzhi winger completed a medical at White Hart Lane, but he's now 3/1 to move there.
However, with Tottenham failing to confirm that the deal had been completed, reports emerged on Thursday evening that Chelsea were now in advanced talks with the player.
Sky Bet's Chris Spicer said: "When we got wind of the news we immediately re-opened betting with Chelsea at 2/1 and Tottenham the even-money favourites.
"However, as the story developed new betting patterns followed and the Blues were quickly backed into heavy favourites to land the in-demand Anzhi star."
"Liverpool, who were favourites over the weekend, are now out to 40/1."
