If Graham Potter wants to comprehend the expectation of success at Chelsea, he need only look at Thomas Tuchel's record in the season before his sacking.
Tuchel won the Super Cup and Club World Cup, reached the FA Cup and Carabao Cup finals, made it to the Champions League quarter finals and finished third in the Premier League. That wasn't enough to save his job after starting this season poorly.
Now Chelsea have turned to a new coach in the hope that he can turn his tactical prowess into trophies.
