It was a cruel introduction to life in the Champions League.
No dream start for Graham Potter as Chelsea contrived to throw away a lead and now they are in serious peril in Group E with back-to-back games against AC Milan ahead. Potter, 47, admitted he had never even been to a Champions League game before let alone take charge of one and for long periods he looked perfectly at home in his new surroundings.
Raheem Sterling scored the first goal of the new Potter era and if Todd Boehly was watching on after punting his idea for a US style All Star North v South game then the Chelsea forward would surely be guaranteed a place. But they let it slip with the familiar failings of Potterball because they dominated, played some pretty stuff - and yet did not put the opponents away.
