But Potter had to momentarily stop his celebrations after spotting an angry Cucurella begin to march over to the Dortmund Players. The Chelsea boss was caught on camera in a heated exchange with the defender, pushing him away.
Cucurella did start walking away, but Potter had to intervene again as the Spaniard tried to make his move a second time. Potter tried to diffuse the situation by pulling Cucurella in for a hug, which appeared to work.
Reaching the Champions League quarter-finals could prove to be a momentum shifter for Potter, who was facing increased pressure at the club following a run of disappointing results. They've won two games on the bounce and will look to keep that momentum going against Leicester this weekend.
