Jamie Carragher believes Man United boss Ole Gunnar Solskjaer will never reach Jurgen Klopp's level of management.
Solskjaer and Carragher had a spat earlier this week after the Liverpool legend questioned Solskjaer's managerial abilities, and the Norwegian reacted angrily to Carragher's remarks.
Carragher has continued to criticize Solskjaer ahead of Sunday's much-awaited match between Man United and Liverpool, believing that the Red Devils boss would never be on the same level as Klopp, Thomas Tuchel, or Pep Guardiola.
Writing in his column for The Telegraph, Carragher wrote: "John Terry was taller than me and was always going to be better in the air. Rio Ferdinand was quicker and stronger. I maxed out with what I had... but nothing I could do was ever going to supplant the two of them. It's the same with Solskjaer up against Klopp, Guardiola and Tuchel.
"He's never going to be at the level of the three managers he's got to beat. He's never going to be them. He's never going to have that gravitas.
"He hasn't got the presence of Klopp at Liverpool, he's hasn't got the trophies behind him that Guardiola has at Barcelona, Bayern Munich, and now Manchester City so that when he speaks the players hang off his every word.
"What intensifies the spotlight is Tuchel coming in. Chelsea were where United have been in the last two or three years but they brought in a manager who has taken them up to that Liverpool and City level really quickly."
On Paul Pogba...
Carragher also referenced Solskjaer's handling of Paul Pogba: "It was a big decision but he and United should be preparing for life without Pogba, who could easily leave at the end of the season.
"I thought it was strong management from Solskjaer to omit him after the player's comments post-Leicester about something needing to change because it's a decision that's largely been fudged until now."
On Sunday, Liverpool go to Old Trafford to face Man United, with the Reds unable to overtake their opponents even if they win this weekend.
