Chelsea boss Frank Lampard steamed into Liverpool rival Jurgen Klopp during last night's defeat at Anfield.
Lampard launched an X-rated tirade at his Kop counterpart during the first half of the encounter at Anfield.
And footage shot from behind the dugout in the Main Stand lays bare the full spat between the two.
After hearing murmurings from the Liverpool section of the dug-out, the Chelsea chief let rip.
“How is that a foul? There's no foul there!" Lampard shouted, taking steps towards the Reds' technical area and directing his ire at Liverpool No.2 Pep Lijnders, who had involved himself in the row.
“Sit down then," declared Lampard as Lijnders returned to his seat in the dugout.
At that point Klopp interjects telling Lijnders to sit down, telling Lampard "calm down, calm down" and beginning to declare "don't talk to my No.2...".
The German can't quite finish that sentence however, initiating a sharp reply from a seething Lampard: "No, no, if he's going off at me, I'll f****** say something!"
Lampard turned and paced to the opposite end of his technical area after a quick word from fourth official Lee Mason, but amid continued declarations behind him - one member of the Liverpool bench stating "it's still a foul" - he soon let rip once more.
"It's not a f****** foul! I'm not asking you. Shut up."
At that point, Klopp, himself growing increasingly irate, yells out "Hey!"
"F*** off you as well!" responds Lampard to Klopp.
"One title you've won and you're f*****g giving it the big 'un F*** off!"
