Alisson will make his Liverpool debut in their penultimate pre-season friendly against Napoli on Saturday following his world-record switch from Roma.
The Brazil international had long been linked with a move to Anfield before the deal was confirmed on July 19, with neither Simon Mignolet nor Loris Karius convincing last term - the latter at fault for two goals in the 3-1 Champions League final defeat to Real Madrid.
Liverpool ended the speculation by finally signing Alisson after the World Cup, agreeing a deal with Roma which could eventually see the Serie A side collect £65million (€73m/$85m).
