Chelsea head coach Graham Potter does not rule out the possibility of going beyond normal time in the Champions League last-16 return leg against Borussia Dortmund.
"Borussia is a top team that has gained incredible momentum. However, we are thinking about keeping a positive attitude. This is our chance to reach the quarterfinals of the Champions League. We will make all the necessary efforts.
The guys are practicing penalties. We want to solve everything in advance, but if not, we are ready," Goal quoted the London coach as saying.
