And so Sunday’s game threatens to be as chaotic as Liverpool’s opener and the 5-3 at Anfield back in July.

That is unless Lampard goes for a particularly defensive formation and system, as he did in several ‘Big Six’ matches last season. Many were surprised by his cautious approach in the European Super Cup 2-2 draw with Liverpool, for example, in which Chelsea sat right off Klopp’s side and waited to counter. Since then, they beat a weakened Liverpool 2-0 in the FA Cup by switching to a 3-4-2-1 formation – and that could do the trick on Sunday.

In this system, the Chelsea wing-backs can get tight to Trent Alexander-Arnold and Andrew Robertson to limit their impact, while maintaining a three-on-three in central defence against the Liverpool forward line. It would also give Lampard the foundation to sit tight and wait for opportunities to play through the centre, with inside forwards Havertz and Mason Mount (who were unusually narrow against Brighton) creating a square in midfield with N’Golo Kante and Jorginho to outnumber their opponents.
