Now plying his trade with Premier League title contenders Liverpool, Alisson enjoyed two years at Roma and won the hearts of the many of the Giallorossi supporters.
The Reds shot-stopper has conceded it took some time to get over leaving Roma after forming a real bond with the club and its fans and he shed many tears when he made the decision to play for his new team.
He told Gazzetta dello Sport: "Leaving Rome was difficult, I cried for a long time and my wife did, too. It's right to be honest, I made a professional choice. I made a step forward in my career and Roma got a big fee. I decided with my head to go to Liverpool but my heart was full of tears. I spent two special years in Rome, my daughter was born there and I have many friends there, even outside of football.
"There were many times that I'd just walk around the city at night. The Trevi fountain is a beautiful sight at night but my favourite place is the Colosseum, you can breathe the history."
Alisson, 26, believes ultimately the transfer was the right thing for him because he has ambitions of winning major honours and believes he can do so under Jurgen Klopp at Liverpool.
He added: "[Staying in Rome] went through my mind a lot because I was so happy in Rome, but when a player decides where to play, it's a much bigger discussion. I have big ambitions, so do Liverpool, and now I'm in the most important league in the world."
