Cesar Azpilicueta had the final say as Chelsea progressed to the Champions League quarter-finals.
Thomas Tuchel's men were temporarily rocked in Lille after Burak Yilmaz's penalty gave the hosts a 1-0 lead in the second leg of their last-16 clash. But the European champions weathered the storm, before Christian Pulisic's equaliser in first-half stoppage time shifted momentum towards the visitors.
Tuchel switched up formation at the break, the Blues took control and Azpilicueta sealed a 2-1 victory on the night and 4-1 aggregate triumph. Not for the first time, the club's 'Mr. Dependable' came up trumps.
