i play him as tranquilista and support.. it means he will come back and help regain possession like in RL, then play DV as target man and Cavani as advanced forward
I play him as AMR inside forward, but tbh with Barca you hardly have to do anything at all. For the lulz I left first half of season to manage for assman and still ended up #1 in the spanish league. After that i decided to find a different job
A trequartista does not try to win the ball back fromt he opposition, that's an attacking midfielder (the majority of the time) a trequartista just looks for space when not in possession. They only provide an attacking threat really, basically, they are a playmaker (like messi in real life)
