The English tactician did not hold back when addressing his lack of anger on the sidelines and in interviews.

Graham Potter is preparing for Wednesday's highly-anticipated UEFA Champions League round of 16 showdown with Dortmund, but with the Chelsea boss coming under heavy criticism lately, the English coach took time to address one key point of contention.

The former Brighton head coach sat in front of the media to discuss the Signal Iduna Park trip, with the English giants desperately needing to win this tie after enjoying only three victories from their last 15 outings.

Due to this terrible form, many have begun dissecting the issues at Stamford Bridge, ranging from the injury crisis to Potter's overall inexperience at the elite level. However, one of the most polarizing critiques of the Englishman has nothing to do with his tactical nous or man management. Instead, some have taken aim at the 47-year-old's temperament.

This isn't something new. Potter, who rarely exhibits anger on the touchline or in post-match interviews, pushed back against this narrative last month, arguing that he is not an emotionless robot.

However, speaking ahead of the Dortmund game, Graham gave the closest thing to a rant since moving to Stamford Bridge. When asked for his thoughts on the claim that he is too nice for Chelsea, a club that became renowned for being ruthless under Abramovich's reign, the Englishman did not hold back.

He flat-out slammed this notion, stating that anyone who holds this belief knows nothing about football given that he started his coaching career in the ninth tier of English football before working his way up.

"Of course I get angry. I'm a human being just like you. It's just that I choose to conduct myself the way that I think is the right way to conduct myself on the side," the Stamford Bridge boss said.

"If you think you can start a coaching career in the ninth tier of English football and get to this point now as the Chelsea and Champions League (head coach) without getting angry or being nice, then I would suggest you don't know anything about anything."

Those were some strong words from the calm and composed Englishman. Check out this moment in the clip below.

While Potter has a point in that regard, the biggest criticism still remains intact. Despite having spent a whopping amount of money over the summer and in January, the Blues continue to struggle on the pitch.

Injuries have played a huge role and there is a need for patience in order for the new players to adapt to the league, the club, and to Potter's tactics. However, the pressure to deliver results remains, and with the London giants sitting 10th in the table in the Premier League, the UEFA Champions League might be the only route to redemption for the Blues.
