Robinho's agent claims the presence of Luiz Felipe Scolari at Stamford Bridge is tempting the Real Madrid forward to ponder a move to Chelsea.
Reports have recently suggested both the Blues and Manchester United are keen to lure Robinho away from the Bernabeu.
Chelsea are reported to have made an offer of 60 million euros (£47.8million) for the 24-year-old, who is upset at his club's plans to include him in a deal to bring United's Cristiano Ronaldo to the Spanish capital.
The west London club deny they have bid that amount, but Robinho's agent Wagner Ribeiro claims an offer for the Brazil international is on the table.
'The Chelsea offer is big, but it's not that big,' Ribeiro said.
Robinho himself has revealed his brief encounter with Scolari at a friendly game in 2003 made a big impression on him, and that he would relish the chance to work with his compatriot again.
Ribeiro echoed those comments, and stated his client is 'seriously considering' a move to London.
He said: 'What's making Robinho seriously consider accepting Chelsea's offer is that Scolari helped him a lot when he still wasn't very well known in Europe.
'Scolari called him up to play a game in Basle, between the Friends of Ronaldo and Friends of Zidane in 2003. Scolari spoke to Robinho and gave him strength.'
It is believed Madrid are reluctant to let Robinho go until the Ronaldo saga reaches its conclusion, and the Brazilian himself has claimed to be happy in Madrid.
But Ribeiro revealed the Spanish champions' inclusion of Robinho in a proposed swap deal for Ronaldo could have caused permanent damage.
He said: 'In the meeting (with Chelsea sporting director Frank Arnesen last week) I said that Robinho was at one of the best clubs in the world, he earns a good wage and today he's known worldwide because of Real.
'Madrid is one of the best cities in the world to live in. In other words he has it all.
'The only unpleasant thing is the club's assessment of his value, and he feels undervalued for having become a part of some trade deal.'
