Alisson has revealed how he was in tears when leaving Roma and almost rejected the opportunity to join Liverpool.
This summer, the Brazilian landed at Anfield from the Serie A for a then world-record fee.
But speaking to Gazzetta dello Sport, the 26-year-old said he was beside himself before deciding to make the switch to England.
"Leaving Rome was difficult," said the Reds shot-stopper.
"I cried a lot, together with my wife. It's only right that I'm honest about it. I made a professional decision, a step forward in my career and for Roma, who earned a huge sum.
"I decided with my head to move to Liverpool, but my heart was full of tears. I spent two special years in Rome. My daughter was born there and I have a lot of friends there outside of football.
"Many times I'd spend the night walking the city streets: the Trevi fountain, in the dark, is so beautiful it moves you, but the Colosseum is my favourite place - you can breathe history there.
"[Staying] 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've got big ambitions and so do Liverpool, and now I'm playing in the biggest league in the world. [Serie A is] not far behind, it's just different and less intense."
