All of roma fans are hoping the same thing like you. Even they were unfurled a banner that said if mourinho shall stay in as roma. Mourinho was able making roma to go to the final two times in a row which never been achieved by the previous coaches since a long time ago.
All of tifosi are supporting him to stay even longer in roma. Mou is still having one match remaining. UEFA also agreed with mourinho if the referee on the match between roma vs sevilla were performing so badly.

The referee was deciding without even seeing VAR. I don't even what's the purpose for VAR if the referee was deciding not to use it to keep the match to be fair?

I hope that he will stay here but it seems like that if he will not move from roma this season.
