Dortmund know Haaland is being wanted by a lot of big clubs, so Dortmund would want a very high price. Sometimes Dortmund often bluffing, by saying the star player is not for sale, but if the offer is big they will definitely agree. Moreover, Dortmund knows that selling Haaland next season the price will fall.
If they can sell Sancho, they will sell Haaland. In history, Dortmund sell many stars: Goetze, Lewandowski, Hummels, Aubameyang. Haaland will not be an exception and he is not a home-grown player of Dortmund. They don't have to keep him in the club and won't face with pressure from fans to keep Haaland.
Haaland is talented but he is another player who just comes and goes.
If Chelsea dared to bid Haaland at a higher price than the last bid, there is a possibility Dortmund accept the offer.
Maybe in the next summer, when Dortmund find another player to replace Haaland. One year for their scouts to search for replacement over the world. Delay one more season like what they did with Sancho and Manchester United. If Chelseas won't give up, I think Dortmund will sell Haaland to Chelsea.
But it looks like Chelsea doesn't want to raise its offer anymore, and now starting to focus on signing Lewandowski. But Bayern aren't stupid either, won't just
let Lewandowski go. Moreover Lewandowski's contribution is very large for Bayern. It is likely that Chelsea will find it difficult to sign Lewandowski,
because Bayern will charge a high price if Chelsea are serious about signing Lewandowski.
Lewandowski is in his thirties and Bayern Munich will sell him if he want to go and if the club for good replacements for Lewy. What if Lewy moves to Chelsea and Haaland moves to Bayern?
It's interesting to see the history of transfers made by Dortmund, because as you said Dortmund have often sold their star players. And it looks like it
could happen to Haaland, actually Dortmund just want a high price to be willing to let Haaland. Because Dortmund know Chelsea really need a striker
and Chelsea have the money, that's why Dortmund continue to reject the offer given by Chelsea. In order to get closer to the close of the transfer
market, Chelsea are willing to raise the bid Dortmund want. Dortmund have good scouts, so it shouldn't be a problem to find a replacement for
Haaland. Dortmund always find talented players, and managed to sell at a high price.
For Lewandowski, I admit that he is not young anymore for a striker, but looking at his performances with Bayern, I believe Lewandowski is still
productive for another 2-3 years. So Chelsea are very interested in buying Lewandowski. There is a possibility that if Lewandowski moving to Chelsea,
then Bayern will go after Haaland, but Bayern will buy it next year waiting for the price to drop.
