I haven't seen a dramatic change from barcelona, last season they finish in 3rd position with 24 wins, 7 draws, 7 loss. This season barcelona rose to 2nd position with 21 wins, 10 draws, 7 loss. But for the style of play, I admit Xavi made a change in the position of the players and that's a natural thing for a new coach. Yes, it's still too new, maybe Xavi needs time to bring Barcelona to UEL & UCL champions
This is quite reasonable considering that in this case he is certainly aware that he still needs a process to carry out his scheme well because apart from improving his position this season he also clearly has to prepare for the next season.
In the last few games even he has always tried some variations in the formation he runs and this is proof that he is still looking for the right formation and team to navigate next season.
Maybe it's more appropriate that Xavi is still looking for some suitable players to be placed in the right position. It seems Xavi wants to return Barcelona to an era where Xavi and the others were still players, compact and fast, that was the Barcelona era of Xavi Hernandez. Maybe Xavi can start by giving Barcelona's young players a chance to play and see their talent
