Dortmund refused to sell lewandowski for 30mil odd to Bayern and chose to rather lose him for free next season. Not sure where you got the "Bayern refused to pay" bit.No they didn't. Bayern refused to pay for him and both himself and Bayern waited out till his contract was up before leaving on a free. There was nothing Dortmund could do in the matter.
Their past transfers.
£32m for Gotze to their direct rivals. That was the buyout but still was a cheap clause to put in.
Kagawa for £12m to United was dirt cheap at the time.
They tried to sell Lewandowski to every top club in Europe at under £30m so he wouldn't go to Bayern on a free.
Do you think they put the low 32mil clause on their own accord? Not sure you realise that Dortmund weren't strong financially like they are now. They couldn't pay their players high wages and we're forced to put release clauses in there and low ones at that. What club willingly puts a low clause?
Kagawa had a year left on his contract unless I'm mistaken.
Sensible decision isn't it considering the alternative is losing him to your biggest rivals for free?
