Chelsea’s record signing came off the bench to score his first league goal since September and win a penalty as Thomas Tuchel's side beat Aston Villa by 3-1 on Sunday.
With Chelsea's Premier League title hopes seemingly slipping away from them in recent weeks, Thomas Tuchel needed a hero.
Fortunately for the Blues' manager and all of the club's fans, he is finally able to call upon his £97.5 million ($136m) club-record signing Romelu Lukaku, and at Villa Park on Boxing Day, the Belgium international showed the difference he can make when he is fit and firing.
Facing a nine-point deficit to leaders Manchester City at kick-off and after struggling for much of the first half against Aston Villa, Lukaku was introduced off the bench for only his sixth appearance since mid-October.
What he produced could yet be the catalyst for the European champions to get their season back on track, as Lukaku first headed Chelsea in front 10 minutes after his introduction, before winning a stoppage-time penalty to seal the points in a 3-1 come-from-behind victory.
As if to highlight Chelsea's attacking struggles this season, Jorginho is yet again the club's top scorer after his brace of penalties on Sunday took his tally to nine for the campaign.
Lukaku was brought in to nudge the Italy midfielder off the top of that chart, but injury and Covid-19 have kept him on the sidelines for much of the first half of the season.
"Hopefully it will not be Jorginho at the end of the season as our top scorer!" Tuchel said in October. "We like him a lot and it is no offence to him, but we want our main guys to score regularly, hopefully, we can provide and create chances for them."
