Jamie Carragher has raised concerns over the form of Alisson and compared his recent performances to that of former Liverpool goalkeeper Simon Mignolet.
The Brazil international conceded three goals as the Reds edged past Leeds 4-3 in their Premier League opener last weekend.
After Liverpool stormed to their first league title in over 30 years last campaign, their defence began to look shaky, highlighted by the 4-0 loss to Manchester City.
Speaking before Jurgen Klopp’s side’s trip to Stamford Bridge to take on Chelsea, Carragher admitted that Alisson’s recent form is a worry.
‘It’s a big concern,’ he told Sky Sports. ‘Basically, Liverpool over the last 12 games have had Mignolet back in goal.
‘That’s what it is, that’s what it’s gone back to. When Liverpool had problems beforehand, before Alisson came in, Alisson in this moment is not making the saves he should be doing.
‘Whether that’s just a blip and he’ll get back to normal, I don’t want to get too carried away, but it’s certainly a slight worry coming here.
‘It is something that needs sorting out pretty quickly.’
Thiago arrives at Anfield off the back of winning seven Bundesliga titles during his time at Bayern Munich, while Jota could provide genuine competition on the wing for Sadio Mane and Mohamed Salah.
