He said: "Yes, it was really hard for me. I am a guy that when I am at home, injured or just resting, I don't like to watch football because I get too excited and I want to play! I want to be part of every game. But I knew that wasn't possible for me, so I tried to make the best of the treatments, the recovery. I spent a lot of time on a bed having treatment, spent a lot of time inside the gym working to be strong when I come back, to be in a good shape, maybe better than I was before.
"This is how I feel. It was eight weeks pretty much working double sessions every day, sometimes three sessions, so it was really hard for me. And, of course, seeing the team fighting for titles, I have a lot of desire to be part of that, to be part of that fight. Thank God I am here and I am looking forward to the rest of the season."
The Reds go to Atalanta trailing 3-0 and Alisson said: "It will start from that. This is a goal not only for this game, this has to be our goal for the rest of the season, for the next season and for the seasons to come. Keeping clean sheets is the basis for a successful team. We did that in the past.
"The trophies we won, we were solid defensive-wise. And that doesn't depend only on the defenders, but from the whole team, from the whole system. We have to defend (with) everyone together, to fight on the pitch to get the ball back, to close the gaps, win challenges, block shots, stop crosses, making saves, making difficult saves. We have to do that as a team to get the clean sheets.
"I think this is a basis for us not only for tomorrow but for the rest."
