Here's the summary of what you have said on this topic :
You will ignore his 10 year of work...only look at the last year...a year where he actually at end mutually quit. 10 years of work which is fully acknowledged by Juve fans, players , media and the chairman, who in the end he was in odds with...Even a failure appoint in Sarri did win the league.
Every one makes mistakes. I dare you to find a DoF who doesnt make mistake. Even the great Monchi , who is well accepted & followed DoF made a huge mess in Roma by selling 230m & buying 200m of flops.
Its one thing to criticise a appointment after some time in job..Its altogether different to belittle and judge him when he actually hasnt yet fully taken the rule.
Anyway, I have said my thing - wont go on any more on this with you
