Suarez should definitively not get a yellow, he's on a roll and we need him the final. Maybe sub him again with Pedro, once we get an away goal...Pedro would press and run chaotically stressing opponents
If one of them has to not play the final, I'd pick Masche...
Dream scenario would be to score early, so that we discourage Villareal and just move the ball around which probably means a less physical game.
No way in hell we must concede first, that will give the yellows the spark they need and the game can go all sorts of crazy from there, pressure, fouls, etc...
