single attacker or a pair?
i have a 433 to be played with wingers and a TM. i use it in arsenal with di maria/ozil/regen as left wingers and deulofeu/walcott as right wingers, with cerci, giroud and a TM regen as lone striker:
GK: sweeper keeper support, pass it shorter, distribute defenders
WB: WB support, cross more often, pass it shorter, shoot less often
CB: CB defend, pass it shorter
DM: DM defend, pass it shorter, close down more
CM R: AP support, close down more, pass it shorter, roam from position
CM L: AP attack, close down more, pass it shorter, roam from position
(both CM are interchangeable, those are the only assimetryc roles on the tactic)
WR/WL: Winger Attack, stay wider, mark tighter, cross from byline, shoot less often (if crosses are not being efficient then i choose a target for them depending on the opponent and who i see is free when i cross)
ST: TM support, pass it shorter, shoot less often.
Control/attack, very fluid
Retain possession, work ball into box, play out of defence, float crosses.
Exploit the flanks, higher defensive line, play wider
Lower tempo, be more disciplined
Contrary to what one may think from instructions, this tactic does not aim to secure possession, it rather uses that shout to reduce the number of players who try through balls just to both AP. You will most likely get between 55-60% possession, not the 60-70% possession tactic aim for. Defensive phase is clearly designed towards high pressing, thus not Half-Back and instead a good old classic DM. If facing a narrow tactic, you can change to play narrower without losing effectiveness. However, defensive line must be high or higher, as all your players look to press on the opponents rather than sit back and wait for them. Same for tempo, i only change the tempo by changing mentality from control to attack. You need slow tempo to give time to your TM, who plays in support duty, and both AP to reach the area. Not slower though, as if used you will lose your advantadge on the wings. I would love to share some screenshots and results, but i am not currently in the computer i play FM, maybe later.
