Have anyone watch the friendly match between Arsenal vs Nurnberg yesterday?
Kai Havertz was playing in left winger position, it looks like he will not replace Odegaard position in attacking midfielder. If Arteta really want Havertz to play in left winger position, he would become a substitute player since Martinelli is solid in that position, same like Bukayo Saka who's solid in right winger position.
To be honest, I didn't watch this friendly match. So, I'm just referring to data and statistics. in fact, Arteta is exploring various options and experimenting with the current squad. as for Kai Havertz, he came on in the 46th minute to replace Reiss Nelson. previously, Trossard had always filled the position. but in yesterday's match, there were several experiments carried out by Artata and Trossard who were played in the midfield position.
IMO, Ateta is doing an experiment. plus, maintaining the fitness of the players. Also in this match, Partey played a duet with Fabio Vierira. while we know, that Fabio Vierira was a very inconsistent player last season. Likewise with the defensive position, Arteta tried to rotate Kiwior. So, this match will not determine the actual player's role, it's just that some players will continue to play their original position.
For Havertz he didn't play badly, in his first friendly. it's just that, I'm sure he won't fill the left wing position. because after all, Arsenal have Martenili and Trossard. it could be, Arteta is currently measuring the players especially those they will put on the sale list. by the way, this is just my point of view.
