Best way to play a 3 man mid?

I currently play a 4 3 1 2 with wingbacks at barca With xavi, iniesta and toure playing in midfield with the following roles- xavi, centre mid- support. Iniesta, centre mid- attack and finally toure ball winner with defence. I had previously played xavi at deep lying playmaker but changed it after he only got an average rating of 7.09 over a hole season, I also changed iniesta's role from ad playmaker as he was gettin similiary low ratings. So I was just wondering if anyone had any tips?

Iniesta - Advanced Playmaker, Attack

Xavi - Advanced Playmaker, Support

Yaya Toure - Box to Box Midfielder / Ball Winning Midfielder, Support

Iniesta did **** playing as advanced playmaker on attack role

Think you've got that pretty much spot on now Phil, whenever I've seen Iniesta he's not playing in the hole as that's where Messi tends to drift into.

He normally pops up everywhere, so attack with high freedom should do a good job.

What philisophy do you use? Try using very fluid, works well for me.

And, don't put him in the right side of the trio. For some reason, he's not perfroming well there.

My setup :

Iniesta - Yaya - Xavi

K cheers il try upping the creative freedom for him see how he performs
