Dortmund's visit a defining moment in Graham Potter's Chelsea story

They are level with Bayern Munich at the top of the Bundesliga after 10 consecutive wins and they have Jude Bellingham. This will not be easy

It is not Graham Potter’s style to make the story about himself. Asked whether knocking Borussia Dortmund out of the Champions League would change the story of his Chelsea career, Potter remained as measured as ever. “I’m not really thinking in that way,” Chelsea’s head coach said. “I’m just thinking about how important it is for the team and the club. It’s a chance to get to the last eight. We’re playing against a top opponent in a really good vein of form. It’s a huge challenge.”

But not an insurmountable one. “What an opportunity,” Potter continued, briefly dropping his guard, briefly letting in some emotion. There was a line about making sure that Stamford Bridge is rocking, and hidden beneath the calm exterior was a sense that this is a defining moment for Potter; a chance for him to win over the fans and prove he belongs at Chelsea.
