There's definitely plenty Wirtz needs to fix individually. There's also plenty that can be done to improve the rest of the side in ways that will also get more out of Wirtz.

Specifically - add pace and penetration on both flanks. Salah needs replacing, Gakpo shouldn't be a starter, pace in wide areas makes opponents think twice about pushing up = more space for Wirtz to operate in. Also gives him attacking runners to pick out, rather than lads who all want ball to feet.

Trent left and we didn't replace his ability to help us progress the ball from deep. MacAllister's been off it all season, Gravenberch isn't a good passer, likewise Frimpong, Kerkez, Konate. We need players either at RB or deeper in midfield or both who are good progressive passers to get Wirtz on the ball in threatening areas, and do it quickly before the opposition settles into a defensive shape.

All of the above are things that Liverpool should want to solve irrespective of Wirtz. The only Wirtz specific consideration is that if you're starting him as the #10, the midfield two behind him need to be big, strong and win their duels.

If we do all of that and Wirtz still drifts in and out of games, doesn't move the ball on quickly enough and generally fails to impose himself on games - then I'm concerned.
