Liverpool boss Jurgen Klopp took a cheeky dig at Manchester United by suggesting his club had saved a fortune by not having to pay off as many managers as their arch-rivals in recent years.

Since the German arrived in 2015 half a dozen people - either permanent or interim - have taken charge at Old Trafford.

Klopp suggested it must have been a costly exercise.

"Imagine the money Liverpool saved from not paying them (a similar number of managers) off," said the Reds boss ahead of Monday's meeting.

"I should have said that when I signed the last contract. It would have been an interesting number."

Klopp admits with so many changes in the United hot seat it is difficult for him to plan for an established game-plan as it is constantly changing.

"Always a different Man Utd," he added.

"That would make me as unnecessary as well if everyone could sit here and it would always look the same, so of course it depends who is in charge.

"They all play different, very different. Van Gaal to Mourinho - that was very different.

"You have to prepare completely differently and we will."

Klopp has had very few bumps in the road since arriving in England, having won the Premier League, Champions League, FA Cup, Carabao Cup and Club World Cup.

Manchester United manager Erik ten Hag

United's latest incumbent Erik ten Hag has endured a difficult start, losing his first two matches, with criticism already raining down on his players.

The Liverpool manager was asked whether he had any sympathy for his opposite number, even if he was in charge of their big rivals.

"No. It's football problems - we have problems," he said.

"I'm not sure if you go to Manchester United and ask Erik ten Hag if we have a few too many injuries (he would sympathise). It is not like this.

"It is not necessary that I feel sympathy. It would not help them, would not harm them. We all have our own problems."

In 2021 Manchester United fans forced the postponement of their game with Liverpool

The German said any repeat of the Manchester United fans' protest which forced their match at Old Trafford to be postponed in 2021 should result in his side being awarded three points.

Thousands of United supporters marched to the ground ahead of the encounter on May 2 last year - which was scheduled to be played behind closed doors under Covid protocols - to protest against the ownership of the Glazer family.

But when some gained entry to the stadium the game was postponed and had to be played later in the month.

With further anti-Glazer protests planned ahead of Monday's match between the two arch rivals Klopp said he does not expect to encounter the same problems but should, for any reason, the match not go ahead he wants to be awarded the win.

Asked if there were any plans in place should a protest cause similar issues, he said: "Plans for the game not happening? Yes, going home on the bus.

"I really hope it will not happen but if it does happen I think we get the points.

"We have nothing to do with the situation and if the supporters want the game not happening then we cannot just rearrange the game again and fit it in somewhere in an incredibly busy season.

"I don't think and I really hope this won't happen - I have no idea what could happen and I don't think about it.

"People tell us we are fine, we go there and play the game hopefully and go home but in a situation like this always the other team should get the points because they have nothing to do with it and they have prepared it."
