"Other clubs finishing in the top four, probably they would like to be in our position, to try to fight for a title".

The 27-year-old has played key role for Mourinho this season and the fact that he has been left out of Wednesday's game points to a potential final start in Stockholm.

"I don't think [he will be available]", he said.
"With two matches in hand that we had to play later".
