Thomas Tuchel did not show his face. There was just a black space where it should have appeared on the press conference Zoom screen and the voice of a man who knows, though he isn't admitting it, that Liverpool and Manchester City look immeasurably better teams than his own.
No, he didn't know when N'Golo Kante, Chelsea's fulcrum who they miss so much, would be back. No, he wouldn't entertain a question about whether Kante might appear again this year. 'It's not interesting what I think,' said Tuchel. 'He has a long way to go.'

The big picture is about where Chelsea's goals are going to start coming from, considering none of their strikers are providing them and a title-winning side needs prolific forwards.
Havertz was a marginal presence. Timo Werner did not start. The pair of them and Lukaku have a collective Premier League goal tally of six. Jurgen Klopp's most prolific three — Mo Salah, Diogo Jota and Sadio Mane — have 28.

Mason Mount was their silver lining. There was a moment in the second half when the 22-year-old seemed destined to collide with Tuchel near the touchline but he danced around him, briefly using him for balance as he
