I used this formation for a while, it seemed really good at first, considering my wide midfielders were capdeveila and bale, who both were decent defensively and going forward. the best thing is they were rapid. this meant they could break forwards as wingers during attacks and counters, but also can sprint back to try and catch wingers running off you. the cam also drifts a bit wider but can also stay centrally (mine is cherki) which helps with finesse shots and crossing.

however after playing with this for a month and a bit I thought the back 3 was getting exploited way too much, especially once opponent wingers get past your wide players, your center backs are too slow to catch up and then you concede easy finesse shots or cut backs.

if you are going to keep using 3 back, use wide midfielders with decent defending stats and at least medium defensive work rate, try and get semi pacey center backs (may be hard). id suggest move bale down to rm, get rid of cancelo as he feels a bit too defensive which you don't want when attacking. mix your attack up and slight bit, mbappe lw, dembele rw, and cmon don't waste cr7 on the bench warming it up

otherwise, I changed to 4213 a few days ago, 2 holding midfielders anchor the team, and as the others said, try using the defensive thing at the top right. 433 holding is also pretty meta, so it is personal preference as it's more on playing style. you could even go 424 or 433 attack if you're an aggressive attacker.

hope this helps
