Simone Perrotta has asked for patience after his Roma side were thumped 4-0 by Juventus on Sunday night.
The capital club went into the game hoping to reduce the gap to third-place Lazio, but they were soundly beaten in Turin.
“Juventus thoroughly deserved the victory, regardless of the penalty,” the 2006 World Cup winner noted. “They are a really strong side and have been built to win.
“Roma? This is still a very young team and we need time to grow.”
The Giallorossi have had a topsy-turvy campaign under boss Luis Enrique.
Although they are only five points away from their city rivals and a spot in next season’s Champions League, they have been inconsistent.
While only Milan, Juventus and Lazio have won more times than them in Serie A [they have 15 wins], only five teams have lost more than they have in the top flight [13 losses].
