Our tactic is to aim for Moore and he's got a few from corners. When he's not on the pitch I'm not sure what the idea is. We seem to hit the keeper every time without him having to move. I'm not really sure what the idea is.
No idea but chipping a football in a straight line for approx 20 yards should be simple. It's not like asking a winger to take on two of three players or someone to score with a overhead kick.
It might help if they concentrated on the flight of the ball, instead of obsessing about nicking an extra two centimetres on the corner arc.
