Thought we can continue our discussion here.
My points are simple - Juve's been winning in Serie A for 7 years. Allegri deserves respect for winning the last 4, but with some caveats. He inherited a well-oiled machine from Conte and the level of competition has been shockingly poor. Napoli and Roma don't have the pedigree, muscle and org know how of Juve. I've always maintained that Juventus will eventually lose their title grip to either Inter or Milan whenever the Milanese clubs decide that enough is enough (and looks like Inter is slowly getting there)
In Europe he did well, but not well enough. Over the years, I thought they were unlucky vs Pep's Bayern and Zidane's Real the year before, but they were soundly beaten in both CL finals by Barca and Real. Allegri couldn't build a CL winning team, which is what the mandate and strategy was all along (after buying Higauin and then later Ronaldo). Last year they were on a clear downward trajectory losing to United, Young Boys, Atletico and eventually Ajax. You couldn't say Juve's exit was unexpected, it was coming.
If you juxtapose CL performances vs Serie A, they were largely being outplayed by teams that are inferior in paper and pedigree. Just look at the Lazio match, should have been 3 or 4-0, Juve ends up winning. Look at Atalanta in the Cup. Look at Genoa. These are teams that shouldn't outplay Juve. Juventus players were just going through the motions and you could tell they weren't motivated by Allegri's tactics anymore.
Final point the meltdown with Adani - the criticism of Juve's style under Allegri is not recent. He was just playing a very boring, defensive football. Once you satisfy the need to win, fans can rightly demand some entertainment, otherwise what's the point. Allegri just couldn't take it, and he just becomes like a rude Mourinho when he's challenged on TV.
Would he be good for Man United? He could possibly steady the ship, but I don't think he would be able to build a title winning team. Just my 2 cents.
