I'm under the impression Mount also looked like an awkward fit in pre-season too, for what it's worth.
And no, I'm not basing that opinion on those two games or the poor pre-season. I'm 99% basing it on the role he's clearly been bought to play for you lot and the fact I've watched Mount play football for 200+ games and don't think he's all too well suited for that. So like I said, credit to ETH if he can eventually pull off having Mount and Bruno in the same midfield together because to the best of my (admittedly limited) footballing knowledge I just don't see how a midfield with those two in it simultaneously can be balanced enough.
It's possible, maybe even likely, that Mount will grow into his new role because I think he's a great footballer but it's also possible he'll struggle with having to play a role he's not experienced in. What I don't get is why ETH wouldn't just sign a player who's already comfortable with the demands of that role to begin with? Just of the top of my head Mac Allister would have been a better fit and I think you could have pulled Kovacic too if you'd promised him a starter role rather than the rotation role he has at City. In isolation I rate Mount higher than both of those two but to fill a midfield that already has Casemiro and Bruno in it I think either of them be better fits than Mount.
I think its a given that given Utd and Arsenal are playing Mount and Havertz in a role that either they are not overly familiar with or will have to re-learn, or at the very least get used to their new clubs playing style and systems, that perhaps it should be a good few months from now we are judging these players.
From an Arsenal perspective, given how crucial Zinchenko and Jesus was to our build up on the left side last season, I think I'll wait until I see Havertz playing in a team with both of those mentioned before judging him too harshly.
I think Havertz has become the scapegoat of this reorganization Arteta had done, which I don't think he actually needed to do. I'm not a fan of the dropping of Gabriel and to invert from the right back position through Partey, so want to see if he continues to persist with it now Zinchenko is nearing full fitness. To me it all seems a bit too forced, trying to fit all of Rice, Partey and Havertz in from the off, when it should be a more natural evolution of moving away from Partey as the season went on.
