Real Sociedad coach Imanol Alguacil says Roma deserved their Europa League victoy on Thursday night.
Roma won the round 16 first-leg clash 2-0 via goals from Stephan El Shaarawy and Marash Kumbulla.
Imanol said, "The result is right and deserved if we analyse what happened inside the penalty areas. We have to improve if we want to reverse the result. A 2-0 defeat is worse than 1-0; we are angry.
"There is still a second leg but if we give away what we did today it will be difficult.
"At Anoeta, we will do everything to put things right. It's difficult to do it against a Mourinho team, who always concede very little in these games."
