"But I don't care how good a centre-back, getting exposed on counter-attacks, you've got to cover the full width of the pitch, it's nearly impossible".
Liverpool will now dust themselves down as they look to get back on track when the take on Hoffenheim in their Champions League play-off first leg on Tuesday night.
"Liverpool are a shambles, all over the place", Carragher said on Sky Sports after 45 minutes. You just have to knock him out the way.
"You've had a pre-season and nothing's changing". What have they been working on?'
Carragher was adamant - extremely adamant - that one player, regardless of how good they are, can not solve Liverpool's shaky defence.
"Whether it's zonal marking, the players he puts in certain positions, the positions of the full-backs in general play are far too high and wide for me, which gets centre-backs exposed". One player's not going to change that'.
"But the stuff about not getting on with Klopp, these stories getting fed out, that's where I think that crosses the line". But Redknapp said a defender of Van Dijk's calibre, would instantly improve the team's performance at set-pieces, as he is a "leader". "They need a leader to head that ball clear". The manager has been there 18 months now but there has been no change.
"That's what happened with the first goal, the corner came from a counter attack, Watford should have been one up before the corner". Carragher was in the process of saying, before Redknapp interrupted him.
Liverpool battled back twice from behind and took the lead in the second, half, only to concede an equaliser deep into stoppage time.
The former Reds midfielder did, though, have some positive words for Sadio Mane, who made it 1-1 with as superb finish and threatened regularly, as he likened the Senegalese to former Arsenal star Thierry Henry. He shakes off Doucoure, good one-two with Moreno and a lovely over Can and it's reminiscent of Thierry Henry in the way he opens his body and bends his shot with his right foot to give the keeper no chance.
