Chelsea overturned a 3-1 deficit against PSG on another memorable night for the club, reaching the Champions League semi-finals.
With Edinson Cavani missing a superb late chance for the visitors, Demba Ba scored a crucial goal to double first half lead provided by Andre Schurrle and send the Blues through on away goals.
The players, manager, and crowd were rapturous in celebration, believing they may again be en route to a very special prize, and emulate their trophy win of 2012.
One man who wasn't especially impressed with their display on the night however was former Manchester United man Roy Keane, who said they didn't play especially well.
Yet as they got the job done, the Irishman conceded, when it came down to it they clearly didn't need to, and simply let their determination carry them through.
He told ITV: "I don't think Chelsea played that well, but what they have with their experience is knowing how to win the game.
"They have desire, the know how to win big games, big characters."
On the night, there was little in terms of statistics to show Chelsea's dominance barring the scoreline. The edged the possession with 52%, and managed just one more shot on target (4-3).
Yet as Keane points out, Chelsea's experienced players, many boosted by the fact they have won the Champions League once before - have the composure to see the job through when the situation demands.
After last night, no matter the quality of their next opponent - nobody will relish a visit to Stamford Bridge in the semi-finals.
