Genuinely don’t understand what you mean here. But to uncomplicate - Bundesliga is a farmer’s league. They have had the same winner 8 years in a row, a winner which until last year, barely looked like winning the CL in that period. They haven’t had a team look like winning the Europa League in God knows how long, and any player above the age of 23/24 playing in Germany cannot consider himself a top player unless he plays for Bayern Munich. If you still play in Germany and don’t play for Bayern in your mid-twenties - you are typically a second rate footballer. At any given time, the only non-Bayern player in the whole country any United fan would want will typically be about 20 years old.
