i find appointing Scouts as Coaches is a surefire topbanana solution.... they only ask for a piddly amount of monay, and yet often have gorgeous stats..... (e.g. Bilbo Baggins at MiddleEarth FC, and Spongebob Squarepants at Cartoon United).
i tend to lose them about 3 months later, once they've proven themselves to be fantastico... but that hardly matters,
coz the current bug in EP2 means that they stay coaching at your club, even though they have moved to another club... and that is mighty nice of them i think !
