I don't think Rangnick just walks into Calcio and just nails it. He's been successful in Germany and in the Austrian world of sports business.
People treating him as a sure thing for clubs on the rise in Germany is one thing, but Milan is already a huge club our last decade notwithstanding, and also the world of transfers and relationships with other clubs seems hard to just walk into without being italian and or familiar with Calcio.
People are cheering on axing the two only positives about our current set up, two directors who have done very well to get our squad in the right direction and who symbolize this club and are talked about with reverence by all of football Europe. Yeah, axe them and give the entire club to Rangnick and Gazidis. The Hugh Janus dream.
Yeah I'm struggling to get that enthused about Rangnick.
Clearly he's successful as a sporting director for RB now and has had great results in 2 short stints managing Leipzig, but only in the unique circumstance of having a dominant club in a smaller league as a feeder club for a project to make a nothing German club a contender. Salzburg were already dominant in Austria before his involvement and he has the support of RB who are clearly very keen to become massive in football and are using Salzburg to build Leipzig. 6 players in the current Leipzig squad were signed from another RB franchise. This seems pretty far away from the situation he'd find himself in at Milan.
Aside from that, in a management career spanning over 30 years he has won almost nothing and only once stayed at a club for more than 100 games. In his times with established Bundesliga clubs he was fired by Schalke and Stuttgart for extremely poor results in his second seasons there and resigned weeks into the start of his second season (which was only 6 months after taking over, including a summer) during his later stint at Schalke due to exhaustion.
The two clubs he stayed at for more than two seasons (as manager) were Hannover and Hoffenheim. He took over Hannover in the Bundesliga 2, got promoted, has a good first season in the Bundesliga and then was fired for a relegation level performance in the second. He took over Hoffenheim in the German 3rd division and got back to back promotions. After 2.5 seasons in the Bundesliga he resigned mid-season citing a disagreement over a player sale.
In fact it looks like he has only once completed a full season with an established club, Stuttgart, when he finished 8th in that full season but was then fired the following February with Stuttgart in the relegation zone and he had to drop down to the 3rd division for his next job.
He's never managed or worked at a club anywhere near the size of Milan, has been fired from the biggest clubs he has worked at after short periods and with poor results and has only achieved success recently and in this unique RB scenario with feeder clubs at his beck and call.
Am I missing something?
