More or less is what I always say, every season, theres 1 man that works in freekicks and 1 in corners, can change the ranking if you add new players or for some reason, but, usually, theres one better for each work. If you find it, is like for me Beckham in freekicks, and Rozomashvili in corners.
Test to find these men really is one of the things that better works, coz as u say every match have corners or freekicks/fouls.
