The offside trap was a risky addition to Diablo. While it could help catch advanced opposition forwards, it also opened up space behind your high defensive line. Most successful Diablo users left this setting off.
Here is a breakdown of the best team instructions to use for the Diablo tactic.
The middle player must have a forward arrow stretching into the striker position.
The Diablo tactic relies on a fatal flaw in the CM 03/04 match engine. The central attacking midfielder (AMC) makes late vertical runs from deep positions. The opposition central defenders fail to mark this player. They drop deep to track the strikers instead.

At first glance, this might seem counter-intuitive. After all, Diablo generated many goals from turnovers. However, experienced players advised against using the counter-attack instruction. Because your team was already set to Gung-ho , checking the counter-attack box created contradictory tactical instructions and could reduce efficiency. Here is a breakdown of the best team

It is arguably the most overpowered tactic ever created in a CM/FM game—a "cheat" tactic that could turn a relegation-threatened side into European champions within a single season.
