The Portuguese tactician subbed Ashley Cole out of his side's 3-1 win over Norwich City on Sunday, replacing him with Eden Hazard, as to prepare the veteran for Friday's World Cup qualifier with Montenegro.
Mourinho said Cole has been carrying a rib injury and admitted he was hoping he would be ok as the Three Lions prepare to host the Montenegrins in a vital clash at Wembley.
"He has had this little problem for quite a while, but now he has it really hard in the ribs area," he told Sky Sports.
"I didn't change him because of that, I changed him because of the options but in the end, the situation before meant it was a difficult condition.
"It is my concern because I want England to do well. I want my players to help their national team and I'll be there Friday because I would love England to go to the World Cup."
