"From the moment I got to Manchester United, I thought of only one thing: building a football club. I wanted to build right from the bottom."<p>The first point is possibly the best. I like how it points at the difference between short and long term development.<p>That said, some managers have become experts in developing themselves over the long term, moving from club to club and eventually learning to win within a single season.<p>Also, some clubs have so much money that they can afford to buy the best players who are able to adapt and perform at any club.<p>The complications are fun to analyse.
