Sacchi says Inter Milan striker Balotelli has long way to go
The Inter youngster has been tipped for a Nazionale call to the 2010 World Cup but his behavioral problems may slow his growth.
"Balotelli is a talent but he is not mature yet," said Sacchi.
"He needs to start playing for the team. If he will prove to be experienced enough or Marcello Lippi is convinced he can help him then he should play for the Azzurri."
