Morata admits Sporting pushed them hard on Wednesday night.
"We didn't start the game well, but this is Real Madrid, and this club and at this stadium this kind of thing can happen. I'm heading home delighted. We believed right up to the end. Until the referee blows his whistle you can win," said Morata.
"I knew James was going to put it there, and I gave it everything I had and it went in.
"Sometimes football isn't fair. I don't know if the result was fair today, but it was vital for us to win and we did that. We've got to try to win the group."
