The 37-year-old believes the Madrid boss has already made up his mind and is set to return to the country where he enjoyed success with Chelsea
The Portuguese coach stated earlier this week he will sit down with Madrid president Florentino Perez at the end of the 2012-13 campaign to discuss his future at the club, but Salgado has little doubt that Mourinho will soon return to the Premier League.
"It would be no surprise if he returns to the Premier League. I think he has made a decision and it will have nothing to do with whether he wins the Champions League this season or not," Salgado was quoted as saying by Sport 360.
"I can see Mourinho returning to England because he loves England, he loves the atmosphere of English football, and the respect English football has for him."
Mourinho previously worked in England at Chelsea from 2004 until 2007.
