I find it impossible to really replicate Barca's possession play. I can average 65% for home games, 70% & a bit in a good game, but I'm never happy with the possession play. Wingers & fullbacks are just ridiculous in how they just run & cross everytime they get to the byline. I've managed to tone it down, but they still do it, & I only want them to do it if it's almost a guarenteed clear-cut chance. I've tried the wingers as wide strikers next to the striker, & it stops them crossing somewhat, but it fails to replicate Barca's width, which loads seem to forget about Barca. They use every inch of a pitch with a player always hugging the touchline of each side of the pitch.
It's annoying though, players always take too long on the ball as if they're trying to look for a vertical pass which isn't on, rather than just aim to keep possession.
