The 21-year old Italian striker, currently sidelined by a foot injury, is set to soon return to action for the Reds and his manager is earmarking an important role for him despite the arrival of Daniel Sturridge from Chelsea.
"Other clubs have the depth to bring people off the bench and make an impact," Rodgers told the Liverpool Echo.
"We have been unable to do that in the opening months of the season, which gives incredible credit to the players who have kept us going until now.
"We have Daniel here now and will have Fabio fit soon and that will give us that spark. Hopefully over the years Fabio can develop into a top performer which I think he can be."
