Daniele Arrigoni was replaces by Sinisa Mihajlovic as Bologna coach earlier this week.
“The problem is that we are making mistakes on the ball that we could easily avoid and that shows that it is a mental issue,” Antonioli explained.
“Looking at the games we have played so far, when our heads are fine we can compete with anyone.
“We showed that in the second half against Juventus and for the whole game against Lazio and Milan.
“Technically we are fine and we just need to restore some self-confidence – we shouldn’t let certain situations get us down.”
