Mihajlovic has very special motivation for Wednesday's Serie A clash, as last season he was sacked to make way for Giuseppe Papadopulo.
"I was disappointed and didn't expect to be fired by Bologna," confessed Mihajlovic.
"We had a very clear plan with the Menarini family owners and I was amazed that they kicked me out before the end of the season.
"Evidently someone else pushed them to make that decision, but in any case, I do not harbour grudges. I am only interested in winning with Catania."
