Chelsea captain John Terry has described his side's Champions League win against Napoli as "one of the very best nights" in the club's history.
Branislav Ivanovic's extra-time goal at Stamford Bridge earned the Blues a 4-1 win on the night and a 5-4 victory on aggregate.
"This is one of the very best nights for us, and we showed what Chelsea are all about," Terry told Sky Sports News. "We were solid and resilient and fought until the very end. We've proved we're a team tonight. Players came in and we stuck together when it really mattered."
Chelsea will now be in the hat for Friday's quarter-final draw.
