BT Sport's German football expert Rafa Honigstein has said he doesn't think there will be any kind of disagreement between the two managers when Chelsea meet Liverpool at Stamford Bridge on Saturday lunchtime.
The two managers have met on four occasions in the past - in the Champions League when Chelsea boss Jose Mourinho was the manager of Real Madrid while Liverpool's Jurgen Klopp was in charge of Borussia Dortmund.
Klopp's side ultimately got the better of Mourinho's Real side by making it to the Champions League final in 2013, after Mourinho's side could only manage to win 2-0 when trying to overturn a 4-1 deficit from the first leg of that semi-final, and Dortmund came out on top in the group stages of the competition by taking four points off Los Blancos.
Mourinho has had something of a history of picking fights with managers that operate in the same league as him, with Arsene Wenger and Rafa Benitez notable adversaries, but Honigstein doesn't anticipate anything like that this weekend.
He said: "They seemed very respectful of each other when they came up against each other when Dortmund played Real Madrid. Of course, [Robert] Lewandowski scoring four goals in that semi-final effectively finished off Mourinho at Madrid.
"I think Mourinho looked at Klopp and he didn't see him as a threat; different league, different level of club and I don't think right now he will start a war with him either - I just don't see it happening.
"Klopp is the sort of guy who is very easy to get along with and doesn't really pick fights unless he feels he absolutely has to - so my best guess is at the moment it's not really going to be anything unusual happening on Saturday, but second guessing Jose Mourinho and what is going on in his mind today is a very difficult game to play. Who knows if he also wants to pick a fight with Klopp? I don't see it at this point though, I think it's going to be all fine."
There is a lot of attention on Chelsea in particular going into this fixture, with the Blues looking to rediscover some form having only won one of their last seven games in all competitions, and are currently languishing in 15th place in the Premier League table having lifted the title just five months ago.
Klopp will be looking for his first league win as Liverpool manager, having opened his account in a League Cup tie against Bournemouth to book his side's place in the quarter-finals. His side are currently three points ahead of Chelsea in ninth place, six points off the Champions League spots.
