Jurgen Klopp has told Frank Lampard he needs to learn to finish arguments at the final whistle and not speak after the game about situations which happen during the 90 minutes.
The Chelsea boss was involved in a touchline spat with the Liverpool manager during the Reds' 5-3 victory on Wednesday night before they lifted the Premier League trophy.
Just one point for the London Blues during the game would have seen them secure a place in the Champions League finishing spots in the top flight however, it was not to be.
One goal that Lampard was not happy about was the free-kick from Alexander-Arnold, which came about after a foul from Mateo Kovacic on Sadio Mane.
The 42-year-old remonstrated with Klopp and the Liverpool backroom staff sat on the bench before fourth official Lee Mason intervened.
A video of the interaction surfaced on social media following the match showing Lampard to have fired a few four-letter words in the direction of Klopp who informed his rival to "calm down, calm down".
That only upset Lampard further, who continued his foul-mouthed tirade towards the Reds boss and muttered about "total disrespect".
Following the game Lampard then spoke with Sky Sports and told the Reds not to get "too arrogant" about winning.

Today in his final pre-match press-conference of the 2019/20 season and ahead of Newcastle United on Sunday, Klopp addressed the situation.
"You cannot hit me or my bench with something like that - we are not arrogant," the German boss said.
"Frank was obviously in a really competitive mood, I respect that. From my point of view you can say what you want in that situation, pure emotion, he came to win or get a point and make Champions League qualification happen.
"What he needs to learn is to finish it at the final whistle and he didn't do that. Speaking afterwards about it like this is not okay. Frank has to learn, he has a lot of time to learn as he is a young coach, but he has to learn.
"We are ourselves, during the game the words he used were not a problem at all but final whistle, as a real sportsperson, close the book and he didn't do that and that is what I don't like, honestly.
"The only reason I spoke about it is because he spoke afterwards and it makes sense to explain what I mean.
"I respect all other coaches. You know how outraged you can be sometimes. You can feel it is unfair."
