heres a helpful tip to score from corners (directly or by a header)
for left side corners you choose a right footed taker like beckham
then (I hope you understand this because its a little bit complicated)
you move the d pad so that the corner flag slightly goes in touch with the midfield line in the radar (when the radar is down the screen) and when the player shoots the corner press the d pad towards the goal so that the ball curves.
little bit complicated but is very helpfull. try to have in your formation a tall striker on the near post , and you'll be absolutely delighted.
