England open their World Cup campaign against Balotelli's Italy.
"Thatâ€™s dangerous isnâ€™t it because you never know, will he turn up, will he not?" says Cahill. "Heâ€™s got the potential to stick it into the top corner from 30 yards. Heâ€™s an unpredictable player but on his day heâ€™s one of the best.
"I played against him a couple of times at City and heâ€™s been tough. I played against him another time when he came off after 60, 70 minutes. Unpredictable. He can be world class. Theyâ€™re just dangerous players but you come up against them every game."
