The perfect formation and tactics!

Best strategy is flexibility. There's 22 places in your squad, use them all wisely.
You don't need 6XCM in your squad or 5 ST. Don't limit yourself being able to play only few formations.
My advice is: get good players on all 14 positions: gk, fullbacks, cb, dm, cm, am, st, wings, central...
More different positons you covered = more playable formations. You can't always counter opponent with quallity, but you can counter him with proper formations.When you have all positions covered, you will be able to adapt and counter every formation.
Use players only on their natural positions.
If you have st, don't use him on cm etc.
