Calciomercato.com says Liverpool will need to break a world-record if they wish to sign Alisson this summer with reports in Italy claiming he'll cost them in excess of £90million.
The Brazilian's international team-mate and Manchester City number one Ederson cost the Citizens £34.7m last summer, a current world-record for a keeper.
But the fee touted for Alisson by Calciomercato would blow that out the water.
He said: “This is the most important year of my career. I didn't want to leave, but I would have had to think of myself and my targets."
