I recently had a save with Leicester and toyed with formations and eventually settled on a 4-4-2 Counter mentality with pressing and Flexible, GK, RB Full Back Defend, CB, CB, LB Full Back Support, RM Wide Playmaker Support, RCM Ball Winning Defend, LCM Box to Box, RM Winger Support, LCF Defensive Forward Support and RCF Advanced Forward Attack. Had an up and down season won the FA Cup after all the big teams were knocked out and finished 6th. Don't have the save any more so can't post an image but might have the tactic floating around somewhere
