An important thing to note with him is he is straight up just not a winger, hes a CF but has played there maybe once for us? He always gets deployed with another striker occupying the spaces that he would be best in. Truthfully this time around im not too upset by him playing on with wing since Victor probably was just that much better in CF in training and you can see from the game he had that he deserved to play there rather than being relegated to the wing.
We can only hope he can get some playing time in his natural position this season
Pau Victor has actually played last games of the season for Barca Atletic as LW with Guiu upfront and he did well there. Definitely also better suited to play on the wing than Roque and if he'll get any meaningful minutes this season with the first team will probably be on the wing (Lewy will be unbenchable) so would make sense to try him out there against a serious opponent (we don't know, maybe Flick already used him as a winger in game vs Olot that was played behind closed doors).

@Porque said confidence is also a thing. Pau has joined first team after playing regularly and scoring 20 goals for Barca Atletic. While quality difference between Primera RFEF and La Liga is big good form can often be brought over from lesser to a higher level of competition so wouldn't be surprised if Pau would also play good at start of the season not only in meaningless preseason games. Happened with Fermin too last year who returned from a succesful loan full of confidence.
OTOH Vitor never had support from Xavi and now playing him out of position I can only see as a GTFO message that is coming from people above Flick so I won't blame him but I do believe he's a "yes man" and it's one of the reasons why Laporta hired him. Even if Flick would like Roque it would still be Laporta's decision to offload him. I think we'll only see what Flick really thinks about Roque if he'll "survive" transfer window here but that's unlikely.
If we would have any common sense we would send Vitor on loan to play regularly and get through next season with Pau as Lewy's backup. That way would also save money on some clauses (for games played) we wouldn't need to pay this season. And I think reasons to move on Vitor are much more financially than sportingly motivated.
I could get behind selling him if that would mean we would get Nico or a DM (or better said defensively strong box to box midfielder who can play in double pivot as don't think we're looking for a pure DM with system Flick wants to play). Not so much for signing Olmo to play him as a LW. I will go out and say that Pau Victor is probably a better LW than Olmo. Or at least that Olmo is not 60m more worth as a LW than Pau.
Club likes Olmo's versatility which is fine and could prove useful sometimes. I don't dislike him as a player but if you're paying big money (and 60m is a monstrous money in current situation) for a player you better do that with a clear role for him in mind not to play him all over the pitch. Xavi already bought Ferran because of his versatility and he's just an expensive bench warmer now. Olmo is a better player and not because he can play multiple positions but mostly if played in his strongest position. Which I'm not sure he would play a lot in, at least this season.
As said in another thread if we're looking for a 10 then I'd prefer to wait until next season and see if we can get Wirtz. If Flick will prove enough to still be here and we'll continue with a 4-2-3-1 and won't return to 4-3-3 under another coach when we won't need AMC anymore. In that case Olmo would probably be another wasted signing despite his supposed versatility. Yes, we could miss out on Dani if we don't buy him now as I don't think he'll stay at Leipzig but while he's a good player he's not a can't miss out on player imo.
