5: Mario Mandzukic - Bayern Munich
Mario Mandzukic's time at Bayern, though fruitful in terms of goals scored, has always looked doomed to end badly.
By this we mean that it's never really seemed like Mandzukic would be Bayern's leading striker for the long-term future, rather that they were using him as a temporary fix until they could land someone more illustrious. Low and behold and the end of this season they're getting their hands on Robert Lewandowski.
This is all well and good but only a fool would think that there will be a starting place for both men in Pep Guardiola's line-ups. It's inexplicable as to why they'd want to replace Mandzukic, but Bayern seem to have their hearts set on the idea.
