Seems to be a lot of 'stop having a go at anyone' going on at the moment.
DF is really poor at shepherding attackers down the flank. Wingers with pace get the better of him coming inside and open us up. He isn't helped by having a striker in front of him but he just needs to run with his man and push him wide each time.
Proffessional football is such an easy game, thats why it always amazes me that experts such as yourself are reduced to posting crap on forums that have no actual connection to the game at any level.
