Bundesliga remains very attractive to players.
Decent wages, great stadia, amazing fan culture, very nice lifestyle and an excellent platform to catch the eye of top CL contenders. Bundesliga clubs in Europe are at least attractive as PL clubs without it. Money talks but it is not the only thing that speaks to agents and players.
Bundesliga is a tremendous league to play in.
Take Bayern out of the equation and the difference between the team is minimal.
They all play a high pressing, high tempo brand of football that is easy to showcase your talents if you're a young footballer.
Added to that, they have big stadiums, they all sell out and it's a top 5 league in the world.
If I were a young player looking to progress, the Bundesliga would be pretty close to the top of my list of choices
