In order to change the corner executioner, press R2 (RT, Shift) and choose a different player from the list. Pay attention to the skills of given players.
A classic corner doesn't require too much effort - the most important factors are choosing the right direction and strength with which you want to kick the ball. In order to perform a classic corner, press the throw in/cross button. It's a good idea to play the ball towards the sixteenth meter - usually there's a lonely player there who can perform a clean and strong shot.
A low cross can be useful to play the ball to the near post towards an incoming player who can try to surprise the enemy goalkeeper with a sharp angle shot. To perform a low cross, press the throw in/cross button twice.
A simple pass is a good option when you don't want to shoot another goal, but rather keep the score at the current level - after passing the ball to the nearest player you can try keeping the ball in the corner or pass it to the back, trying to draw enemies away from your side of the field. In order to call in a player, press the run button.
