Former Liverpool captain Graeme Souness has claimed that a "question mark" hangs over new Reds goalkeeper Alisson Becker.
The Brazil international completed a £67m move to Anfield from Roma last month, which made him the most expensive keeper of all time in terms of transfer fees.
Alisson subsequently kept a clean sheet on his Liverpool debut as Napoli were beaten 5-0 in Dublin, although the 25-year-old's performance was somewhat shaky at times.
"A goalkeeper was clearly a priority and Liverpool have broken the world record for that position by signing Alisson from Roma for £67m," Souness told The Times.
"He played in Brazil and Portugal, then was initially kept out of the Roma team by Wojciech Szczesny, who found English football difficult at Arsenal, so he's not coming with 300-400 games at the highest level under his belt and, despite the fee, there has to be a question mark against him."
Alisson is expected to replace Loris Karius as Liverpool's number one goalkeeper for the coming season.
