The first four tactical options are one-off moves, i.e. if you switch them on, the move will occur just once. 

Offside trap (D-pad up then up) will rush your defence up to play the attack offside.

Team press (D-pad up then down) will push your team up on your opponents.

Swap wings (D-pad up then left) will cause your two wingers to switch flanks.

CB joins attack (D-pad up then right) will get one of your centre backs to play alongside your strikers.

The other four tactical options change your whole side's tactical set-up. 

Counter attack (D-pad down then up) will cause your side to sit deep and then throw players forward on the break.

High pressure (D-pad down then down) will create constant pressure on your opponents.

Possession (D-pad down then left) will bring your players closer together to keep the ball with less movement.

Long ball (D-pad then right) will get your strikers further forward and move men closer to the frontmen to feed off the knock downs. 

Pressing down then left on the D-pad will cause your players to move closer together in a bid to retain more possession. Use this tactic if you are looking to protect a lead.
