Mourinho has demanded that Gareth Southgate explain why Sterling pulled out of England duty due to the Tottenham boss' firm belief the winger will feature against his side tomorrow.
Sterling left Southgate's group as a precaution after a calf strain sparked an injury scare.
He said: "Of course we all know that Sterling is going to play tomorrow. When Eric Dier left the national team injured in the previous month, he didn't play two matches.
"And Raheem is going to play tomorrow. These are the little details that I think Gareth should explain."
