Chelsea are the odds-on favourites to beat Tottenham to the signing of Willian after Sky Bet re-opened betting on the Brazilian's future.
The online bookmaker suspended the market earlier this week as the Anzhi player completed a medical at Spurs, but he's now odds-against to move to White Hart Lane.
However, with Tottenham failing to confirm that the deal had been completed, reports emerged on Thursday evening from Sky sources 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."
