The Reds paid a world-record fee for Alisson.
New Liverpool keeper Alisson Becker says he already feels at “home".
The Brazilian trained with his new team-mates for the first time at their training base in France following his move from Serie A side Roma.
"It has been a great day which I had been looking forward to," Alisson told Liverpool's official website.
"I've had a good few resting days with my family but we all couldn't wait to get the new season under way soon. It's only my first day and I feel at home already."
