But the problem is that Vincent Kompany led Burnley to the relegation zone last season and even though he also led Burnley to promotion to the EPL in the same season, he should not have sent his former team back to struggle from the bottom. On the other hand, he doesn't have much experience in handling a big team like Bayern Munich and this is the basis for my assessment.
What you say about Burnley is very true, but don't you realize that it will be difficult for any coach to bring his team to compete in the English league without having a capable squad all this time, you see the kompany failing at Burnley without seeing what the basis of its failure so far, apart from that, when you believe that De Rossi can make Roma better last season, why should you doubt Kompany capacity now in munich, when both of them are completely inexperienced coaches, Alonso and Arteta has a positive effect on their first big team so far, but if you look at their journey so far, isn't it impossible that Kompany can also do it with Bayern Munich which is filled with many star players next season.
Talking about De Rossi, he managed Roma before but failed. However, after that, if I'm not mistaken, he stepped aside from coaching any club and after that he was appointed again as Roma coach. From my point of view, during that time when he was not working he must have fully learned to develop new strategies and when he became Roma coach he was ready for the challenge. So here the difference is quite clear and Vincent Kompany has to prove that he is as capable as De Rossi or other coaches if he doesn't want to be labeled as a minor.
De Rossi career journey is no different from that of Kompany today, De Rossi previously coached the SPAL team in the Italian league but he failed to make SPAL even better but instead was recruited by Roma to replace Mourinho, while Kompany career is actually still better in my opinion than career owned by De Rossi because after all he was able to handle Burnley before quite well even though he failed to keep Burnley in the Premier League, apart from that, De Rossi, who you might think is better than Kompany, isn't this season he just continued the performance and squad left by Mourinho?
