The arrival of Jules Kounde could see Xavi play a dynamic formation with three centre-backs in his defence.
That could see a player like Raphinha play alongside Ousmane Dembele on the right wing.
Here’s what the lineup will look like:
Regardless of who Xavi decides to use at right-wing, a back-three has often proven to be defensively difficult to break down – Xavi has tried it before with good results.
Barca are also a powerful team in attack, particularly with the arrival of Robert Lewandowski. That means solidifying the defence with this formation will make the Blaugrana extremely difficult to beat.
