This is why Raphinha should start on the RW while Dembele should start on the LW.
It have worked so far this season, but Xavi decided to switch it up and use Raphinha as a left sided attacking midfielder. I know some people are going to post a page full of stats and xG graphs to show how Dembele is better on the RW and versus shit teams he really is, but in games like these you cannot have Dembele be the only creative outlet and let him have the ball 90% of the time because he has never shown good decision making in a game like this 5 years into his Barca career.
And no Ansu cannot start because Ansu looks shockingly bad physically so it have to be Dembele on the LW whenever he is available.
