Hard to say tbh xavi is doing pretty decent at the moment his footballing ideas are the same as peps. The big issue is we have a good team but as of yet due to financial crap we don't have the great squad to properly compete how we want to
what I DO know is he wouldnt win UCL just like he hasnt with any other team in last 10y.Xavi is closer to Big Sam than to Pep. One of the most boring and draining style of plays I have seen.
Just because he's a Barca legend and started out with a 433 doesn't mean he's Pep.
Anyways, he ended up preferring a variation of the 442 with 4 mids and 2 forwards. Xavi is Big Sam without the anti relegation grit and shithousery.
