Real Madrid forward Robinho should complete his €36m (£28.7m) transfer to Chelsea in time to make his debut in the home derby with Tottenham Hotspur, according to his agent Wagner Ribeiro.
Ribeiro said on Wednesday night that he expects his client to be a Chelsea player 'by either tomorrow or Friday,' adding in the The Daily Telegraph, 'he should be available to [Luiz Felipe] Scolari for this weekend'.
Robinho, along with Deco, who has already made the switch from Spain to Stamford Bridge, were selected as Scolari's main transfer targets when he became manager of the Blues in the summer.
Chelsea chief executive Peter Kenyon shares Scolari's desire to lure Robinho to London and believes the Brazilian international can take the club to the 'next level'.
'He's the right age and he comes from Madrid so he understands what a big club is all about,' Kenyon said.
'What we're doing is supporting Scolari. He wants to change and move the style a bit [and] is confident about the player's ability and mentality and that he will fit in and make an impact.'
Chelsea had two bids for the 24-year-old rejected by Madrid earlier in the transfer window but the La Liga club's desire to use Robinho as a make-weight during their pursuit of Manchester United's Cristiano Ronaldo has unsettled the player and he now wants to quit the Santiago Bernabéu.
He is expected to receive a salary of £70,000 a week at Chelsea, double his income at Madrid.
Robinho is expected to wear the No7 shirt vacated by Andriy Shevchenko, who has rejoined Milan two years after Chelsea signed him for £30m.
Chelsea are so confident of concluding the deal with Real Madrid that fans can already buy Robinho shirts at the club's online megastore
Meanwhile, there seems little prospect of another Brazilian, Kaka, leaving AC Milan to join the Blues, not least because the playmaker is happy at the San Siro.
Chelsea were linked with a world-record £80million bid for Kaka, but he told Italian sports daily Gazzetta dello Sport: 'Me going to Chelsea? I'm staying as a Rossoneri player.
'I should help Milan to win the trophies we're up for this season.'
He added: 'I've always said I'm happy at Milan and as long as my aims remain the same as Milan's I'll stay here. Until now it's always been that way.
'My goal is to win, Milan's is too. As long as we are like that, I'll remain at Milan.'
