During his career as a manager Gattuso never last long in the particular clubs even the latest is he was messed up in Marseille which caused this team not qualified to the champion league and now surprisingly football federation of Italy has been choose him as Italy manager which this move is very risky
As far as i know Italy not qualified to the world cup 2 times in a row 2018 and 2022 so Italy people are expect this time their country can playing again at the world cup and Italian fans has high expectation to Gatusso
Gattuso had a better playing career than he has right now as a coach and am not really expecting much from him, He didn't do much at Napoli, or Valencia or in Marseille. So, I really do not see any reason to justify his appointment as coach of the Italian national team boss, but it would be better if he is given the benefit of doubt to see if things might get better for him especially now that the team's chances of qualifying for the world cup is already in jeopardy as a result of Luciano Spalletti's flops during Italy's last encounter with Norway.
We can't judge the finality of his coaching career. As you said, give the benefit of the doubt here as he may have not shown his full potential yet as a coach. He was a very good athlete before so we may not be seeing his strategies in play right away as a coach. Give him time and see what he can do for the team. I understand, a lot of people are judgmental. It is still early to make a conclusion of his coaching career, right?
Once the team starts winning under his wing, people will surely change their hearts on him.
