Balotelli causes fireworks on and off pitch

Mario Balotelli can be one of the world's top three players if he can cut out his eccentric behavior, Manchester City manager Roberto Mancini said after the striker's two goals inspired Sunday's 6-1 rout of Manchester United.

Currently staying in a hotel after setting his house ablaze by letting off fireworks indoors this weekend, Balotelli was equally explosive in the derby at Old Trafford.

After netting a 22nd-minute opener, the 21-year-old Italian lifted his shirt to reveal a T-shirt with the words "Why always me?", leaving Mancini with just one explanation.
