Tavecchio appears to claim Juventus players stopped Insigne playing in Italy's World Cup play-off against Sweden.
"I don't know if the Juve players didn't want him, but the facts tell you there were problems deploying Insigne..." Tavecchio told Radio Kiss Kiss Napoli.
“How could you not play Insigne in Milan, even in front of 20-30,000 Neapolitans, who were there that night?
"That night it would have been appropriate to play the more technical players, among other things.
“I'm the one with the least responsibility, I resigned because no-one else would."
