Mourinho has been linked with a return to Chelsea at the end of the season, and although the Portuguese coach has publicly stated that no decision has been made regarding his future, Salgado has admitted that he does not think the 50-year-old will remain in Spain.
The former Spanish international told Sport 360: "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.
"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."
Chelsea won two Premier League titles under Mourinho's leadership before he left the club in 2007.
