I came up with this idea after the summer, while I was raging about how ridiculously stupid the Arsenal board is. So, basically, what you do is that each summer transfer window, you sell your captain and your best (or next best) player. If there are any players with a year of contract left, sell them either in the summer or in January. Replace these players with promising youth. Also, you never spend more than you make during the windows.
Any feedback/suggestions/additions? I suddenly want to try this. xD
