Unsettled Manchester City striker Robinho underlined his desire to leave Eastlands on Sunday and stated a loan return to Santos is '90 per cent certain'.
The Brazil international was quoted by Radio Bandeirantes over the weekend as saying that he was set to leave City because he would not be guaranteed regular football by Roberto Mancini in a World Cup year.
City's manager announced after Sunday's victory over Scunthorpe in the FA Cup that he expected Robinho to stay in England during the January transfer window.
But British-record signing Robinho, who started and scored against Scunthorpe, is also quoted as saying on Sunday in an interview with TV Globo that all that is left to negotiate with Santos is the time period of his loan.
He said: "It's all good progress. Santos are only looking at the length of contract because they want a year and City want only six months but I think it is 90% sure."
Robinho, who has also been linked with Benfica, added: "Santos are talking to the staff of City and I think that within three days we can define it all."
The former Real Madrid player's time at City has proved disappointing since he arrived from Spain in a £32.5million deal in September 2008.
He has been criticised for failing to show full commitment by some City supporters and news of his desire to quit the club is likely to further damage his popularity.
Robinho, who turns 26 on Monday, said in his interview with Radio Bandeirantes: "The coach was very sincere with me and said that I would play every other match.
"I told him that would not be interesting to me, it's a World Cup year."
