Assisting the opener and netting the winner - Fernando Torres had a good weekend.
But it was more than an assist and a goal for Torres, Sunday reminded us all what an incredible footballer the Spaniard is.
Back in his Liverpool days, Torres would terrify defenders before even setting foot on the pitch, and with his mystique plummeting since his move to Chelsea, yesterday was a slap in the face to those who write Chelsea off for their lack of firepower up front.
Torres in yesterday's form is head and shoulders above an ageing Samuel Eto'o and a frankly average Demba Ba.
The former Atletico Madrid finisher was a constant threat against Manchester City, running the channels, taking on his man and getting in behind.
The Spanish striker worked his socks off for his team, inspiring the other Chelsea players with his level of commitment.
Some good work down the right set up Chelsea's first - scored by Andre Schurrle - and he was rewarded for his performance in the final moments when he capitalised on a defensive mix-up to give Chelsea the lead.
Many expect the Gunners to fall over the coming week with a series of difficult fixtures, and Chelsea could capitalise on that - with Torres the catalyst for the climb.
Witnessing Torres back at his explosive best - he almost scored a wonder goal from the edge of the area, rattling the cross-bar - is a joy to behold.
He has at times appeared sluggish, but the £50million man was as bright as you could ask in Sunday's crunch encounter.
Having missed a sitter earlier in the game, Torres could have let his head drop, but it seemed to motivate the Blues striker further.
In a season that was heralded as the return of Jose Mourinho, it could be the return of Torres that catapults Chelsea to the title.
