Jordan Henderson came on as a second-half substitute against Torino to make his first appearance of the summer, having been granted extra time off following the World Cup.
Liverpool were able to field only one senior centre-back in the 3-1 friendly win over Torino last night.
Carragher is among those feeling confident, with additions suggesting that Liverpool will be in the mix for the Premier League crown as positive foundations from 2017-18 are built upon.

"Hopefully he will go on to be a great goalkeeper and be remembered for that but Liverpool had to make a change because I think there would be no belief in Liverpool actually, never mind winning a league but challenging for the league with the two goalkeepers they had". "But I'm happy we can start at the weekend because pre-season is good but the season is better still".
