Redknapp believes the problem rests squarely with individuals and has called for the club to spend big on Virgil van Dijk while Carragher is of the opinion that the manager has to take the flak.
Neville then asked for evidence of Carragher's demise after Watford equalised, and Twitter replied with videos of Carragher having a meltdown with co-pundit Jamie Redknapp.
"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".
It takes their tally to 27 goals conceded from set-pieces during Jurgen Klopp's reign - the most racked up by any of the top-six during that period.
"On average Liverpool conceded around 50 goals a season".
"I don't care what defenders they go and buy, how much they're going to cost, it won't make a difference. He wouldn't be in Firmino's position (for the corner), he would have been in Lovren's or Matip's because they'd have been coming out of the team".
Alongside the 39-year-old in the Sky Sports studio on Saturday, Jamie Redknapp attested that the arrival of a leader like Van Dijk would give Liverpool dominance in set-piece situations.
But that just acts like a red flag to a bull for Carragher, who continues to rant and argue with his colleague, as you can see above.
'They play so high and wide that they have a centre-back exposed there all the time.
'It's nearly impossible. What defenders can do that?' Van Dijk will improve it, yeah, but one man can't change it all'.
"I don't like the fact he's giving him the chance on the back of pre-season, he knows the players, he's had him for 18 months". If you want to win the Premier League, you've got to be conceding 30-35 goals.
"I think Lukaku will get goals for them, especially in the games where they dropped points, at home against weaker opposition".
"We're still seeing the same things year in, year out, and it went back to Brendan Rodgers as well".
The first concession came via a corner (a set-piece, which becomes the centre of discussion), as Stefano Okaka was unchallenged, allowing him to head at goal from only a few yards out.
