Exactly, It must be admitted that the Italian league has become a boring league after Inter, AC Milan and AS Roma lost momentum to build a quality squad. It is difficult to say, if I want to speculate, the Italian team is struggling to bring in a quality coach because it is difficult to fulfill the coach's ambition to bring in the players he wants. Financial problems are faced by big teams like AC Milan, which until now have not been able to bring in a promising coach. Even though in the second half of the season after restarting the league, they performed well, but from a financial perspective they were still not doing well. The same thing happened to other clubs. So maybe this is the reason why clubs in Italy are difficult to bring in quality coaches.
I think about recruiting recently retired players as coaches is not just to take risks, but they are like making bets for luck. Of course, their prices are also much cheaper than hiring an experienced coach with a good coaching history.
