Charles De Ketelaere could hardly believe his luck as neither Benoit Badiashile nor Marc Cucurella came to challenge him. Chelsea's defenders backed off, deeper and deeper until in their own box, and Atalanta's impressive attacker scored. Just like that, Enzo Maresca's bad week got worse.
The 3-1 loss at Leeds was embarrassing, the 0-0 draw at Bournemouth was boring, and those two performances told us why they are not yet true Premier League contenders. In all likelihood, as good as Chelsea have been as a tournament team under Maresca, this season's Champions League is bound to be beyond them also.
