Stramaccioni had said Cassano was going to start this game, but instead he was on the bench.
He said: "I wasn't trying to confuse anyone with mind games. The truth is he had a sore neck and I was the one to change my mind at the last minute. He remains the form striker.
"I thought a midfield with Gaby Mudingayi, Walter Gargano and Esteban Cambiasso was the best way to approach Bologna. I knew we had to keep Alessandro Diamanti quiet, so would do that by sending him into the areas against Javier Zanetti and Walter Gargano."
