I'm in the middle on this one, yes Marotta did his fair share of mistakes. Yes, there were many happy to see him go and yes, the appointment of ticci influenced our feelings for the great man. Its a hindsight bias.
We were not to know how incompetent ticci would turn out. We did know how difficult it became to sell marottas dead wood, tici decided to use his own valuating algorithms in helping to do that. Inter will have the same issues that we had, but they also have a team that is built to deliver in short term. Finances screwed us, buying low selling lower worked till it could, on the other hand ticis buy higher sell low screwed us even more. That said marotta was great for us, but not for one to win our CL obsessesion, unless he got lucky. Helping us to win countless leagues, shouldn't be taken away from him. Agnelli wanted us to go the next level, but knows we don't have the finances, yet he goes and approves the buying of Ronaldo because somehow that will improve our finances. Agnelli reminds me of the kid who always looks over at their rivals to see how he can improve, and then thinks as entrepreneur and gambles like it's his first business. Stability was important, and for that marotta should be praised (other than the 90m higgy fuck up).
Right now, we need marotta again, but once we're back on top of serie A, I agree we need to find a better replacement.
