Lewa is already in gr8 situation in Bayern
People should be able to differentiate between "unsatisfied" and being eager for better situation .RM may offer more money but that won't mean that Lewa would be unsatisfied
Same way that a guy like Marquinhos probably would love to join Barca but there is zero chance it would happen . PSG won't let him go and the guy isn't desperate for the move because he is already in a good situation
Same with DDG right now ,after his move to RM already collapsed
If the guy accepted not being sold to Bayern and played well with BVB in his last year ,I doubt Bayern would feel he would be a team cancer or won't give 100% if they forced him to stay
Those clubs have so much ego mate ,if they want the player to stay until the very last day of his contract it will happen
90% of players feel great on his current clubs and still transfers keep happening window after window.
Comparisons with Marquinhos just doesn't make any sense, because Barça was never intending (or even capable) to make him the most well paid defender in the world. And he surely didn't deserve it too.
In the end, he just didn't have enough incentives to ask PSG to trade him.
Madrid, on the other hand, CAN and probably WILL offer astronomical wages for a must needed high profile forward, especially with Benz and Ronaldo being departed for a squad rebuild, accordingly to rumours.
Anyway, as I already said, Lewa is not unsatisfied. But money (I mean HUGE MONEY) can make a monk turn in to a rebel, imagine a football player.
About Dortmund, again: completely different situation. He was six months from being free and Bayern was willing to wait.
He didn't miss the opportunity, he just delayed.
Madrid cannot wait and this train stops only once.
