A goalless draw at Real Sociedad home in Spain with Roma means Mourinho men are into the Europa League quarterfinal after holding on to a 2-0 first leg victory.
After winning the inaugural UEFA Europa Conference League last season, Mourinho is leading Roma towards another likely European success.
Stephen El Shaarawy and Marash Kumbulla score in the first leg to put Roma in the advantage of qualification and they ensure there was no upset in the second leg as they played out a goalless draw.
Roma has a goal disallowed for handball and Real Sociedad has a player sent off caps the tenacity and heat of the game.
