The Italian scored his first Premier League goal for the club during the 6-0 drubbing of Newcastle at St James' Park on Saturday.
"What made it even better for me was that it came in front of the Liverpool supporters so I could celebrate with them.
"I just wanted to thank them for the support and they have really helped me through my injuries.
"It's been hard. When I hurt my shoulder, they said my season could be over. But I fought back as I really needed to come back earlier.
"I took the minimum possible to get back training which was eight weeks instead of 12. Some people probably didn't think I could make it but I fought back.
"We have always been together as a group and I think the performance against Newcastle showed that.
"I can play a big part now not because Luis Suarez is suspended but because I am back fit. Whether Luis is available or not, we all need to focus on doing our jobs."
