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
I don't think it's too good if he still sticks to things that have passed, considering that in this case no matter how hard he does, the results will still be different and won't be the same as their heyday era some time ago. but it does not rule out he still has a chance for his prime at Barcelona but has to be at a different rhythm now as those past benchmarks were quite difficult to run with their current squad.
Btw I'm quite impressed now that he's made a quick move in terms of player transfers. at least there are defenders who join there.
