Alisson hopes he can prove to be a value-for-money purchase at Liverpool – just like superstar forward Mohamed Salah.
The Brazil goalkeeper made the same switch Salah completed a year ago when he moved from Roma to Anfield for £65 million (£83m) last month.
That deal made the 25-year-old the most expensive goalkeeper in history, although Kepa Arrizabalaga took that weighty distinction off his hands when he joined Chelsea from Athletic Bilbao for £71.6m ($91m) this week.
Salah cost the Reds £36.9m ($47m) – a fee that raised eyebrows at the time but is now considered a major bargain given the Egypt international's stunning 44-goal campaign in 2017-18.
