Graham Potter enjoyed his finest night as Chelsea manager as they overcame a first-leg deficit against Borussia Dortmund to reach the Champions League quarter-finals.
Potter was under huge pressure after a dismal run of results following Chelsea's huge outlay in the transfer market, but he will hope the manner of this performance and the advance into the latter stages of Europe's elite competition will deliver a measure of calm and stability to Stamford Bridge.
Chelsea fully deserved their win, although they squandered several big opportunities before Raheem Sterling made the breakthrough after 43 minutes, firing past Dortmund keeper Alexander Meyer after initially fluffing his shot.
