Attacking roles are heavily bolstered by Pace, it's been this way on FC Pro Clubs for years, and it's no different on FC 25 Coins. When earning skill points for playing online games, players should look to max out their Pace if they are in an attacking role (ST, LW, RW) before putting their skill points into anything else.
After max pace, players should look into stats such as dribbling and shooting to maximize their success. The best shooting and dribbling in the world can't do anything if a Pro is too slow to move past any defenders, which is why Pace is the most important skill for players to focus on as it's some of the best strikers in FC 25.
Just like with every other game mode, players can affect the tactics in their club, stuff like build-up play and defensive tactics. These affect the way the squad sets up and marks the opposition, so players should take great care when affecting their tactics. Having the best left-backs in FC 25 won't mean anything if a team doesn't have conservative tactics.
Building the tactics to be very attacking-based can leave teams open to the counter, so taking a more conservative shape in the tactics is a great way of maintaining some control over the team without leaving the team open to a counterattack.
Players can affect the height of their Pro in the main menu of the Pro Clubs game mode. It is advised that players either make their Pro very tall or very short. The benefit of a tall buy Fut 25 Coins player is that they will win nearly all aerial duels, which is very useful if the Pro is an attacking player and the team is getting a lot of corners. On the other hand, players can make their Pro really short but have them have a base level of speed that's higher than taller players have.
