Joe Cole has praised Kai Havertz for stepping up to retake the penalty that booked Chelsea's place in the quarter-final of the Champions League.
Raheem Sterling's emphatic first-half finish sent the hosts on their way to overturning Borussia Dortmund's 1-0 advantage from the first leg before Havertz sealed victory on the night and progression into the next round.
Chelsea's second goal was not without drama. Potter's side were awarded a penalty after Marius Wolf was adjudged to have handled the ball inside the area and Havertz actually missed from the spot the first time of asking.
