He hasn't played one way. His tactics have changed to counter the opposition. Most games we play 4321 to fit in Shaqiri, which then reverts to defensive 4-5-1 when we lose the ball. I remember one game where Phil Couthino played deep midfield and pinged balls up to Sturridge up top in the 2016/2017 season. I would not call it tactical genius, though. His stubbornness means that he believes in his tactics. if he kept changing it, the players might lose confidence in his ability. It has worked for him. They were calling Unai a tactical genius earlier in the season! Not so sure, now, eh?
