The win keeps Roma’s hopes of finishing in the top-four in the Serie A alive.
Montella said: “I saw a good performance and we dominated the first half, even if we sometimes held on to the ball for too long.
“We sat back a bit too much in the second half, putting less pressure on their midfield, then there was the incident that led to Lecce’s goal.
“The fact remains our hunger won out and we deserved the victory, as in terms of quality and overall performance Roma did better than Lecce.”
“It is a psychological issue that made the team tense after conceding so many goals in the same period of games,” Montella added.
“That is why the fact we pushed through and even won it at the 90th minute can be a real turning point. We’re on the right track, but can still do much better.”
