The player himself has declared himself fit to play and has passed all medical examinations. Ivano Bonetti has therefore announced he will be in the first team squad.
Whether he will actually play in such a torrid atmosphere of a derby is a matter of doubt, though. Lacking match practice for some time, the tackling in these games is usually the most notable points, rather than the skill factor.
I believe he will be there to motivate the others. His presence in the dugout alone should be enough to ensure 100% from his admiring team mates.
