Gigi Del Neri has admitted that Roma deserved to beat his Juventus side in the Coppa Italia last night.
Despite having the home advantage, the Old Lady struggled to break down a capital outfit who qualified for the semi-finals with a 2-0 victory in Turin.
"It was complicated," the Juve boss noted. "We found a Roma side who were very motivated, very alert, who played an excellent game.
"We had difficulties, also in terms of fitness, with regard to injuries rather than our work rate. The players who came off did so because of injuries and not for tactical reasons.
"Martinez had some issues but I could not replace him because Simone Pepe had his own problems. Amauri had to come off and I had to play Iaquinta whose not featured in a while.
"We couldn't do any more as a side given the situation we are in."
Juventus rarely threatened in attack but did worry Roma when Alessandro Del Piero and Philippe Mexes clashed in the box, but no penalty was given.
"At times penalties, or certain incidents, change the psychological effect on a game. It happened at Napoli with Toni's disallowed goal and today we were not awarded a penalty," Del Neri added.
"We produced what we could, we sent players on to the pitch who hadn't played for a while.
"We need to play better and I think we'll be able to do that. You shouldn't forget what we had achieved up until December.
"It's clear that we must now use all our energy in a very complicated championship."
Juve face Udinese on Sunday but Marco Motta, Pepe and Amauri are all doubts after picking up injuries last night.
