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.
