Sergio Aguero only managed to play 46 minutes against Arsenal on Saturday morning, but he certainly made them count.
By the time he left the game, he'd already scored his 13th Premier League goal in 15 matches and was one of City's best performers, buzzing all around the pitch from his attacking position and providing a constant threat.
WhoScored.com gave him a 7.7 match rating for his efforts, another strong showing from the in-form striker.
As seen in his goal, what makes him so special is his ability to take advantage of any chance that comes his way. He is anything but wasteful.
It will be the knock that is of primary concern, however. The leg injury didn't look good, as Jamie Jackson of The Guardian noted:

You can practically hear the City faithful still holding their collective breath.
At the moment, it's hard to deny that Aguero is one of the two best strikers in the Premier League.
While Luis Suarez has been in otherworldly form since return from his biting suspension—a remarkable 15 league goals in 10 matches—Aguero has been red hot as well.
But if he is forced to miss any time with his injury, City will be in trouble.
Yes, the Citizens are a deep and talented squad, but Aguero has been the key man thus far with his pinpoint finishing. For as talented as Alvaro Negredo or Edin Dzeko are, they aren't nearly as clinical as their Argentine teammate.
And as he showed against Arsenal, there's a piercing nature to Aguero's game.
He finds the spaces behind defenders, runs out wide and takes players on, seeming to have that natural ability to be in the right place at the right time that the best strikers possess.
His goal off a corner kick embodied all of those qualities.
He creeped toward the back post, expecting the ball to be flicked back his way, losing his defender. He took the ball on the volley and sliced it into the net with pristine form.
It was a forward's goal, and set the tone for the entire game.
Aguero's first-half performance was strong, and City enjoyed a 6-3 win over Arsenal even without him. But if he is forced to miss much time, the Citizens will most certainly struggle to replace the impact he has on the game.
