The Italy coach says the Inter forward still has a part to play at the international level, but competition for places means he is no longer guaranteed a place in the squad.
The Inter forward played a starring role in the Azzurri's Euro 2012 campaign but has since been snubbed by his nation for their opening World Cup 2014 qualifiers.
“We are lucky, because in this moment we have a lot of strikers," Prandelli explained after being awarded the Tor Vergata Ethics of Sport Award. "However, the door is still open for Cassano because he is a good player. The same for [Antonio] Di Natale."
The 55-year-old coach then gave his thoughts on the rumored dispute between Roma coach Zdenek Zeman and Italian duo Daniele De Rossi and Pablo Osvaldo.
“I don’t like it when the players argue with their coaches. I believe they only should think about playing football," Prandelli said.
