Dortmund advanced 1-0 on aggregate after winning the first leg at home, but a goal in the early half by Raheem Sterling and a contentious penalty by Havertz cost them at Stamford Bridge on Tuesday.
Ben Chilwell’s cross struck Dortmund defender Marius Wolf’s outstretched hand in the second half, earning Chelsea a penalty.
Havertz’s penalty attempt hit the post, but the penalty was retaken after VAR informed the referee that players from Dortmund had entered the penalty area. Havertz scored on his second attempt, advancing Chelsea to the quarterfinals.
“I’m not sure what more he can do with his hand,” Bellingham told BT Sport, referring to Wolf. “That in itself was disappointing and the fact that they’ve had a retake, I think it’s a joke.”
“For every penalty, especially when you have such a slow run-up, there’s going to be people encroaching into the box by a yard or so. He has made the decision and we have to live with it.”
Dortmund coach Edin Terzic said his team would refrain from complaining.
“If a decision takes about five or six minutes then it’s not easy to make a call,” Terzic said.
“But as the manager of the team, I’m responsible for the performance of the team and staff, but not the performance of the referee. We didn’t speak about the referee a lot last week and we won’t start with that tonight.”
