That's a tricky opinion. We mustn't forget that from a players perspective he is leaving the team he loves, a team from his country where he is close to family, and one that's paying him a decent salary than a team that's not as big in comparison at the moment, in a league that's not as visible alongside the likes of the EPL and La Liga, and last, but certainly not the least, the money on offer is less than what he is being paid currently. From a fans perspective we can question his approach, but in his shoes I reckon I'd do the same.
If Goetze goes elsewhere this summer, then I'd disagree with that theory. However, if he chooses to stay on the bench for Bayern, then to me at least, I'd say our salary cut offer was not good enough. It's one thing to consider his differences with his club, that could get us a slightly better transfer fee, but because of his age and talent, he is not at a point in his career where he will need to take a pay cut to ply his trade and he's aware of that. Doesn't make him any less of a professional than Draxler, who as his agent has claimed considers his future every summer. Ambition isn't just linked to playing regularly or in a certain profile of team, it is also linked in a very big way to money, and it applies across cultures and sport.
Yes, and why should he? If he doesn't move to Juve this season, he will easily end up next season at another club that will at least match his salary if not pay more.
So if Juve could sign CR7 or Messi, you wouldn't sign them? The club is growing, it's business is expanding, and eventually it is going to come to working with bigger salary caps, because it comes with the territory. Those higher salaries are what's going to keep players happy, and help the club retain its core and sell more jerseys over a longer period of time, and get bigger sponsorships. Whether you or I want it or not, eventually it will happen.

I am. It's amazing how simple everyone thinks it's going to be. It's not.
