I’m guessing Xavi received orders from up above to play 4-3-3 after last season’s boring haram ball.
Whatever the formation, it’s still more attack minded (vs a midfield 4). Like the idea of us being more of a threat down the middle instead of us always passing out to the wings.Doubt the formation has changed much into a 433.
Unless it is Yamal LW and then would be more like a 4231.
