Chelsea's manager and fans had hoped all week that Samuel Eto'o would be fit to return for their Champions League clash, and their prayers were answered.
But little did they know it would be a player regarded as third choice in Demba Ba who would prove to be the club's saviour, scoring the goal to take the Blues through into the semi-finals.
Eto'o was ineffective and illustrative of a striker not 100 per cent fit, with substitutes Fernando Torres and Demba Ba looking lively even before the goal.
The Cameroon international paid tribute to his teammates after the game to his fellow strikers, with a Twitter post saluting the 'brave' duo who came on and played their parts - in many ways answering the criticism of their manager after the first leg.
Mourinho had claimed after the first leg he was lacking 'real strikers', with Eto'o injured for that match. Demba Ba for his part illustrated why he would feel he deserves more opportunities, and even Torres looked like he was springing into life.
Chelsea's flagging season has been given a welcome shot in the arm, and at this stage nothing can be ruled out - as they showed us two years ago.
