In some ways, it's a shame Anfield wasn't at full throttle when Frank Lampard shouted at Jurgen Klopp for 'f***ing giving it the big 'un' when Liverpool played Chelsea in July 2020.
But in others, it's brilliant that the stadium is empty and the exchange was clearly caught for all to enjoy. And it was something to enjoy, no matter how unedifying some might have considered. The needle between two rival managers on the sidelines is something we rarely get to hear.
For those who may have forgotten, it was sparked by a foul on Sadio Mane - Lampard was furious at the referee's decision while Klopp felt Mane was being targeted by Chelsea.
