Remember the old Chelsea? They were the side that, no matter what else was going on, turned up for the big occasions.
That included the Steven Gerrard slip, that night at the Nou Camp and even last year's FA Cup final with Antonio Conte heading out the door. Now, after losing to Liverpool, they have lost their last six away Premier League matches against fellow 'big six' opponents, conceding 16 goals across those defeats.
More than anything, that is what Maurizio Sarri is struggling to cope with as Blues boss. Chelsea have lost their big game mentality.
