I am having trouble winning 50/50 balls in the air like a keepers punt. So what button do I push so my guy will go up for a header?

Next...can I send a guy on a run during a corner kick?

Any other hints?

hold d/shoot to contest a heading shot at goal.
I fu want to aim your header elsewhere as a low header hold s/pass and as a lob header a/lob
make sureyou hold the button until the ball hits the head, and point wheer you want it to go..
