I'm cool with the image on the right. I'd rather see Kylian Mbappe on the right but since he'll be wanting to score goals, he'll be playing more in the middle as the central forward.
The likes of Vinicius Junior and Rodrygo also would definitely thrive from the both wings, hopefully they don't be selfish amongst themselves, this could be the fastest clubbin history especially when attacking.

As for Jude Bellingham behind the strikers? He is not an attacking midfieder, I'd rather see Luka Modric or Àrda Guler behind them. These are just predictions anyways.
The defense has always been solid, Carlo Ancellotti recently came out to say they won't be expecting any further signatures until next season.

I think we'll be seeing both Alexander Arnold and Alphonso Davies signing up for Real Madrid for a free transfer same strategy with Kylian Mbappe.
Barcelona will thrive this season but they need quality players honestly, otherwise, It'll be another season like the one Xavi Hernandez had last Session/Campaign.
