I recently played a couple of people over Xbox Live, one was Aston Villa, the other was Barcelona (Ibrahimovic and Carew being their massive target men) and they were hitting the byline with their wingers and really whipping the ball in, like it would curl right across the goal over the keepers head and Ibrahimovic or Carew would always be there to nod it home. The curl was mad, like you wouldn't know where it was going to land.
I tried a few techniques, desperate to repeat their feats, such as holding "RB" while crossing and using "LB + X". However, neither worked, and my crosses keep either floating into the box, before being cleared, or not beating the first man.
Does anyone know how to really whip the ball in, is it as simple as pushing the left stick in a certain direction while the ball's in the air, or is there actually a technique to it?
