I created a "Van Gaal" formation for my Sassuolo save. 3rd season. Finished 2nd after the mega-God Juventus, won Coppa italia and Europa League last year. Here is it: (sorry I cant post any images because the game is not on this computer)
Keeper: Mattia Perin
Complete wingback: Manquillo (on loan)
CB (defend): Antei
CB (cover): Barzagli
CB (defend): Darmian
Complete wingback: Leandro Villaba (from River Plate)
BBM: Gaston Gil Romero
RPLM: Florenzi (luckily got him for 7.5m when he was unhappy at Roma)
APL: Saponara
Complete Forward: Simone Zaza
Advanced Forward: Domineco Berardi (goal scoring machine)
Team instruction: short pass,work ball into box, pass into space, look for overlap, get stuck in, close down more
This also works for my Soceidad save. Hope you would take a look at this. Feel free to ask me questions. Cheer mate
