I don't have much expectation from Gennaro Gattuso to be honest. He doesn't have a successful history with any team as far as I'm concerned. He got sacked most of the time because of not meeting the expectations.
I wonder whether they tried to convince a better coach instead of him. For example I would have liked to see Mancini.

He is without team since October 2024. He won a Euro championship with Italy earlier as you know.
If they hadn't tried - it's unlikely they would have gone straight to Gattuso. I agree, it's not the best option, but whether it was a mistake will only be realised after the team's official performances, not before. Moreover, it will be very difficult to judge on one match, and the result is expected as a rule immediately, fans are not patient
