re: Chelsea fans gonna hate

Roman knows plenty about building a team, but running a club isn't like a video game. Teams have ups and downs, injuries happen, players are unfamiliar with one another, sometimes tactical problems are difficult to diagnose, sometimes players start playing badly for no reason, etc. One of the reasons Wenger and Ferguson are so successful is that they have a system in place they stick to even when everything is going against them. That becomes important, because it helps average players hide their deficiencies, and the whole team can rely on that system when everything else seems to be falling apart.
