I haven't played the new patch yet, and I'm considering not installing it. I never really had a problem with corners. I spend 10 mins nucking around with them a couple of months ago and I score at least once every three games. Don't know what the fuss was about. Wonder if I'll go on a 3 season unbeaten run on the new "easier" version of FM08.
No - get your best header/jumper to challenge the goalkeeper than set corners to 6 yard box. Also get your second best defender to attack near post, and any other good headers to attack ball from deep.
