Simply signing Southampton defender Virgil van Dijk will not be enough to solve Liverpool's serious defensive frailties, former Reds defender Jamie Carragher has insisted.
Liverpool were 2-1 down at half-time and Carragher was less than impressed with the two goals conceded by Jurgen Klopp's side from Stefano Okaka and Abdoulaye Doucoure.
Speaking on Sky Sports following Watford's last gasp equaliser, Carragher was scathing in his assessment of the Reds' defending as a whole - not just their back four - and expressed his frustration at Klopp's insistence on utilising a zonal marking system at set pieces.
'Why Firmino is the central man I will never know, he should be blocking him (Okaka) but no one does in the most risky position in the six-yard box.
"Nothing changes, what have they done pre-season?"
You can't help but feel for Carragher. 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.
"They play so high and wide, if you're a centre-back you're exposed all the time, it's culture". One player's not going to change that'.
"If you're a centre-back exposed there all the time..."
"He will help, but on set-pieces it's not about the defence".
"One man isn't going to improve [set-piece defending], that has got to come down to the manager", he added.
"The way Liverpool set up, set-piece-wise, they're always going to concede goals".
"It's the setup of the manager, he's been here now 18 months: set-pieces are the worst in the league, conceded the most goals of the top six, there's still no change".
"You think where they were weak last season: set pieces, getting done on the counter-attack, that's what happened with the first goal - for the corner - it comes from a counter attack".
He said: 'There is a reason why they concede so many goals, because they are disorganised there and have no leaders at the back.
"On average Liverpool conceded around 50 goals a season".
"If you're Van Dijk's agent you've got another 20 grand a week on his contract after watching that".
"I think Manchester United will be in there, they didn't make the top four past year but I think they will with the additions that they've made", he said.
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.
'There's a bit of energy and spark when he gets the ball and it's a wonderful goal'.
