It is no coincidence that almost all of the major titles over the past five years have been won by big-spending superpowers – the only real exceptions being Dortmund's back-to-back Bundesliga crowns and AC Milan's 2010-11 Scudetto.
Football today is dominated by money, and how this money is used in the transfer market largely determines the success and failure of a club, at least at the very top end of the sport.
Quality will always be the main consideration for the elite when buying players. Bayern Munich recognized after losing the Champions League final on home soil 19 months ago that the club was only two or three top-class purchases away from going a step further. Thus the club was prepared to break the Bundesliga transfer record and blow 40 million euros on Athletic Bilbao's Javi Martinez in order to cure its main positional weakness.
