Bayern Munich Club is the most consistent in terms of games, enjoyable to watch even the last 10 years, nothing is as consistent as Bayern in terms of games.
It proves that individual players do not attract much attention to German teams, let alone expensive and big players, deserve to be a strong team because they prioritize teamwork.
You could say that Bayern are stingy in their finances, they make up for cheap players with good quality. The results are also good, rather than buying expensive players but not according to the criteria. Nowadays, clubs are competing for expensive players just for a business.
I don't really agree that Bayern only has cheap players. I mean just look at their squad. Kimmich, Goretzka, Davies, Musiala, Coman, Gnabry, Sane, Mane and De Ligt all have a market value of 60 M€ or higher. Also the total market value of it's squad is higher than the one of Real Madrid, FC Barcelona, FC Chelsea and Manchester United for example. Bayern is ranked on 4th place in terms of total market value of it's squad. So i would say that Bayern Munich has a very high quality squad with absolutely great players but yes of course it is true they never went for that absolute superstars like Ronaldo or Messi.
Also Bayern had absolutely no debts like all the other top clubs, Bayern even has Money still sitting on the Bank and all that without that crazy high English TV money and without the financial help of sheikhs and oligarchs.
