'Yesterday, he sent me a message saying: "Hey, what are you waiting for?"
And three-time World Cup victor Pele is also hoping Alisson can thrive at Anfield, as the 77-year-old sent a message to his compatriot on Twitter.
Their £57m transfer of Aymeric Laporte in January and the £60m transfer of Riyad Mahrez from Leicester this summer have each broken City's club-record fee twice within the space of two transfer windows.
Alisson made 37 league appearances for Roma last season and helped the club reach the Champions League semi-finals, where they were knocked out by Liverpool.
Liverpool have not won the top-flight title in England since the introduction of the Premier League, but look as strong as ever going into a new season.
Alisson broke the world record transfer fee for a goalkeeper after completing his move to the Premier League side for £65m.
"That game definitely did have an influence but I also watched other games". The league is different, the refs are different, the goalkeeper life is different in the Premier League.
"I think that's fantastic as I love being part of a dressing room that gets on so well, and where we're all pulling in the same direction".
Of course, for a club whose entire fan base remains traumatised by the performance of their goalkeeper in June's Champions League final, none of that really matters.
It is possible that a low-profile save monster will end up with more points than Alisson in the Goal game, but he has the potential to be an elite goalkeeper and should be owned as such.
"I'm really happy to have the opportunity to play alongside him again".
With van Dijk stationed in front of him and Liverpool's defence in general showing signs of improvement last season, the signs are positive for Alisson's debut campaign as an FPL asset.
The newest additions to Jürgen Klopp's squad have yet to see competitive action for Liverpool, but they are already making a big impression on the training ground.
