I'm really fed up with Bayern Munich's buying every one of talented players from Dortmund.

I'm not happy to hear that Bayern Munich could be interested in adding Erling Haaland to their squad in case Lewandowski decides to leave the team because of this. Please, just let these players go to other leagues a little, man. If Haaland is leaving for real this summer, then I would like to watch him in other leagues from now on. The Bundesliga is one of the top European leagues of course but not as big as the English Premier League for example.
Here we have nothing new because if you are able to check history it's already happened many times Bayern buying quality players from Dortmund and enjoying this all for some seasons and then dropping them out and Dortmund management never try to use them for having their own better results they mostly love to buy players and then sell them to big teams for higher prices.
As now, we are checking Bayern is interested into Haaland then no matter they will buy him and having very strong attack even now Lewandowski going to leave Bayern for another club. Right now, Dortmund is looking for their desired amount and this is going to happen because after end of this season surely he is going to leave, and now we have only two clubs with Bayern is front and second one is Real Madrid.
