How to attack with the 451 Flat in FC 26?
They key attacking philosophy with the 451 Flat in FC 26 is overloading the opponent's box with runs off the ball and create space with your first touch to score goals. You are looking to play one or two-touch football with stop-start football confusing both your opponent and their defensive AI with "La Pausa".
One of the subconscious effects of strong defensive AI is that people don't manually press the ball carrier much, hoping for an AI interception or block at the edge of the box. Your goal is to exploit that by holding the ball at a stop and looking for player runs, sometimes even manually triggering them to make space for yourself.
With wingers running in behind, your striker holding the backline and both your LCM and RCM looking to make late runs into the box the opportunities for a cutback are rampant here.
Look for the extra pass, don't try to rush your play or you will fall prey to the overpowered tracking of defenders, use the pause strategically and bait the press to play balls in behind to score easy goals.
How to defend with the 451 Flat in FC 26?
With a strong defensive line of FIVE players in midfield, your job is to make sure that your defensive line isn't leaving any unnecessary gaps open with aggressive pressing. Use your LM and RM to track wide players carrying the ball down the line.
The goal is to stop the cutback manually while forcing your opponent into errors by playing through a congested central area and get their passes intercepted.
Don't be tempted to bring your CBs or CMs out of position when they are twisting and turning with the ball, they are looking to bait you and open up a gap in your structure to exploit, use your wide midfielders to create pressure in the middle instead and you will make them play the game on your terms instead.
