Roma coach Paulo Fonseca was pleased with victory over Torino.
Roma fought back to win 3-2 on Wednesday night.
“The team feels much more confident and secure, we created numerous chances to add more goals this evening," Fonseca told Sky Sport Italia.
Roma have been transformed since switching to a three-man defence, but Fonseca admits it's not his preferred option.
“To be honest, I prefer the other tactical system, but the team gave a much better response to the 3-4-2-1, so that is what we're going with. We had also tried it in our first game against Atalanta, so it wasn't entirely new.
“All our fans tell us they want to win the trophy, we want it too, but know it won't be easy. Sevilla have won the Europa League five times, so we have to think about them first and then we'll see what happens."
