Italy manager Cesare Prandelli has suggested that Mario Balotelli will have to fight for his starting spot in their World Cup opener against England on Saturday.

Ciro Immobile and Lorenzo Insigne have impressed by contributing goals in the Azzurri's 5-3 victory over a warm-up match against Brazilian club Fluminense on Sunday.

"Clearly we have some healthy competition up front," the Daily Star quotes Prandelli as saying. "Everyone has a chance. Whoever doesn't play will have to accept the choices. Potentially there could be a lot of stars in this squad."

Balotelli last scored for Italy in October.
