not a tactical expert but generally speaking 5 at the back rarely works in FM22, Better to use a 4-3-3 which in theory shouldn't be too different from your current formation, prob get one of your CMs to be a MEZ on the IF side, and on the other side either a BWM or BBM oh also for defenders have one as a normal defender and the other as a Ball playing defender
you might want to remove play for set pieces are you are risking injury, injuries happen regularly already, having extra ones is just a pain in the ass, also with the suggestions I gave you it would be good to play slightly shorter passes and higher tempo
distribution should be to the centerbacks and full backs to avoid unnessecary loss of possesion, spur players are more than good enough to do some prime barca tiki taka until they get to the front, and I think that's all you really need to change
