Manchester City may be anxiously waiting to see if Sergio Aguero will be fit to face United on Thursday evening, but Puma appear to believe he is raring to go after launching a new football boot especially for the game.
The Argentine limped out of Sunday's FA Cup semi-final in extra time and Pep Guardiola later confirmed he will face a fitness test ahead of their Premier League clash against their city rivals.
Puma, like every Citizens fan, will be praying he passes it as they have gone ahead and launched the Derby Fever evoSPEED SL-S boot, designed in conjunction with Aguero, who plans to wear them in this week's game – and this week's game only.
