Wenget plays the odds. Everything he does is based on percentages and risk. From injuries, to squad depth, to player positions and tatics.
Its the same with transfer fee versus player potential. Sometimes it works, sometimes it doesn't, but he has unwittingly lowered the level of quality in doing so.
Wonder if he's losing his nerve though - now he is tapping second tier 'established' players, and fucking up badly with his punts...
