waiting for Victor Roque next year is not difficult for Barcelona. I'm sure Xavi can come up with a strategy with the formations used even with the existing players. Lewandowsky is indeed very important on the Barcelona front line. but I still believe that if Xavi lets Lewandowsky rest, Xavi can still use other options. Ferran Torres cannot be a replacement for Lewandowsky. but it looks like Xavi will have a special formation that makes him comfortable playing.
Xavi still has Ferran Torres, he can play in various positions. despite the fact that the player did not show good performance last season, he can still be used as an option if Lewandowski suffers an injury. and if the signing of Vitor Roque goes according to what was originally planned, he could become Lewandowski's backup. although still relatively young, it seems that Xavi really believes in this player from Brazil. a few days ago there were rumors that Barcelona wanted to sign Vitor Roque as soon as possible.
But as reported by Romano, Paranaense still relies on Vitor Roque until this December. the Brazilian club wants Vitor to stay and qualify for the Copa Libertadores. So, this player will be planned to join Barcelona in the 2024 winter transfer window. but if Barcelona can bring him in sooner than originally planned, they will have a young centre-forward on hand to back up Lewandowski should he be injured. after all, if we refer to Barcelona's pre-season matches, it seems that Xavi has prepared several strategies that he can implement after conducting several experiments.
If I refer to what you said, the 4-4-2 formation is more likely to be a defensive pattern. ideally Xavi applies the 4-3-1-2 pattern, this pattern suits their offensive style of football. yep, like when Barcelona countered Real Madrid in the pre-season match. so with the players that Barcelona currently have, Xavi can apply the pattern as he wishes, but it all depends on which team will be their opponent.
