Peter Walton has clarified the correct decision was made when Kai Havertz was ordered to retake his penalty after both Chelsea and Dortmund players encroached on the box.
The former professional referee was called upon to provide insight on what played out at Stamford Bridge on Tuesday for BT Sport after referee Danny Makkelie spotted an infringement as Havertz hit the post with his spot-kick.
Makkelie ordered that Havertz take the penalty again - which the Chelsea star scored - after players from both teams encroached on the box, with Walton explaining that the match official made the correct call.
