A new manager wastes money on transfers: don’t let him
Use the wisdom of crowds (take opinions on players from a number of coaches)
Stars of recent World Cups or European Championships are overvalued: ignore them
Certain nationalities are overvalued (Brazilians and Dutch, for example)
Older players are overvalued
Centre-forwards are overvalued; goalkeepers are undervalued
Gentlemen prefer blondes; identify and abandon ’sight-based prejudices’ (blonde players are, sub-consciously, disproportionately popular with scouts because they stand out from a distance)
The best time to buy a player is when he is in his early twenties
Sell any player when another club offers more than he is worth
Replace your best players even before you sell them
Buy players with personal problems, and then help them deal with their problems
