An incredibly uncommon formation, the FIFA Formations 4-5-1 Attack is among the most attacking systems in FIFA 20. Instead of three central midfielders, two will push on into attacking midfield roles, giving lots of assistance towards the striker. You are able to either choose to have fluidity involving your attacking and wide players or remain regimented and press your opponents. Possess a play around with custom techniques to see what performs. What's most crucial is the fact that your central midfielder stays back on the attack, and also you may want to perform precisely the same with your full-backs.

FIFA Expert's recommended work rates:
Right Back – Medium Attacking / High Defensive
Left Back – Medium Attacking / High Defensive
Right CB – Low Attacking / High Defensive
Left CB – Low Attacking / High Defensive
Right Mid – High Attacking / Medium Defensive
Left Mid – High Attacking / Medium Defensive
Central Mid – Low Attacking / Medium Defensive
Right CAM – Medium Attacking / Medium Defensive
Left CAM – High Attacking / Low Defensive
Striker - High Attacking / Low Defensive

Strengths: Definitely has a case for claiming to be the best formation for retaining possession of the ball as it has a bit of everything. The wide players provide key width to your play and the CM acts as the main playmaker which can provide the 2 CAM's with ample space to join in with the ST to create plenty of goal scoring opportunities. 

Weaknesses: The main problem which most people will find with this formation is the CM can sometimes become a little lost and caught out of position if you're not used to using them as the focal point of your play. The tendency is to try and get the 2 CAM's involved quicker which can backfire as they won't have as much space to play. RM & LM's with low defensive work rates can leave you exposed on the wing so try to have a medium for both attacking and defensive work rates for these players.

Key player/position: CAMs. If used correctly and taken full advantage of you will be able to work plenty of room for your 2 CAM's to cause lots of problems for the opposition defense. Unless there are 2 CDM's on the opposite team (not many formations will have this) then the 2 CAM's are going to find lots of open space to play in which in turn can be very beneficial for your team and the attacking opportunities this will provide.

Most suited style of play: Possession play and a slow-paced build-up passing style.
