Right now he is a mixed bag.
One thing he surly likes: PLAYMAKING AND PASSING
Past few games (probably since Sevilla games) we aren't Messi dependent anymore on build up, and that is even when we moved Messi to be our AM (his natural position atm).
Coutinho, Pedri, Pjanic are all involved in playmaking, Fati is developing nicely in that area, same with Trincao
Griezmann is also involved in passing and connecting with other attackers, Busquets is always a passer, Roberto is a playmaking RB and Lenglet is great in building from the back.
Even in his subs, he takes Alba for Dest, who is better in passing and crossing.
This fits with the Dutch idea for 4231, where playmaking is appreciated and 2 or 3 of the front 4 are actually no10 who are switching.
In the long run, this is great as it is developing our possession & creating ability. But atm? we are most likely doomed.
Team atm has no one to score in penalty area, closest thing to that is Fati but we played him as n09 only one game. With Messi bad finishing we are doomed in scoring abilities despite all the chances we create.
In addition, we lack speed in the team, only Alba provide that along Dembele, the later is inconsistent at best. Dest is quick but he is yet to show it in attack.
Our defensive set up still leaves a lot to be desired, same with our inability to be more cohesive when being pressed, but honestly huge part of this has to do with personal in his had, as I mentioned many times lack of quick CB and winger hurts in those areas.
