Corini played for Guidolin at Palermo.
"Eugenio was my greatest captain, an excellent player, a leader and a sensible, intelligent person," said Guidolin.
"You could tell at the time he had the qualities to be a leader. He already held that role at Palermo, even if we also had other great players.
"Eugenio is now trying, as far as I can see with good success, to put his own ideas about football into action.
"I had advised him to quit a year earlier and join my staff, but he wanted to continue playing. I wish him all the best in this difficult line of work."
