Pellegrini hails five-star Aguero

Argentine striker in awesome form against Newcastle

Manuel Pellegrini has revealed Sergio Aguero required halftime treatment on a hamstring injury before his remarkable five-goal spree in Manchester City's 6-1 demolition of Newcastle.

After failing to score in five league games, since netting against Chelsea in mid-August, Argentina forward Aguero claimed five goals in 20 minutes and 27 seconds at Eastlands on Saturday, making him just the fifth player in Premier League history to score five times and the fastest ever to record that feat.
