How do some of the coaches in Europe get the reputations of being one of the best coaches in the world when they have only coached for teams that are stocked with the some of the best players on the planet. For example Pep was the coach of Barcelona that have no problem buying the best players available that money can buy like Suarez, Neymar, and already having Messi even a halfway decent coach should win games and trophies with that kind of team. Then he goes to Bayern and already has powerhouse team built and to no surprise he wins games. Mourinho is the same way, he coaches clubs with deep pockets that are already built to win and can afford to go spend 200million in the transfer window. I am just curious of what makes these guys stand out as some of the best coaches in the world? Why not the guy who starts with a tiny budget with lesser known players and brings home silverware?
I am not knocking these guys for doing what they do I am just curious to how they would do with a team like say Atlanta United with a limited budget starting from the ground up. Could they come in and win or are they only as good as their owners wallets?
