it working for me, aswell as anybody on post, but u guys conceding with it, maybe i have just luck, i don't know really.
ofcourse, sometimes something drop into my net, but it happens even with two posts cover, so i personally decided to take one post cover man to marking man instead.
After playing some more games with the new corner changes you gave me I've conceded less from corners now it only happens here and there so thanks.
