I still feel like our ideal setup would be a more output focused midfielder (a #10 essentially) in the right 8 with Odegaard playing a bit deeper in the left 8 role focused more on buildup and playmaking, but with less box crashing than Arteta has Rice/Merino doing currently. My dream setup had always been someone like Wirtz coming in and playing the right 8 but now I'm starting to think Nwaneri would be a perfect fit there. The only issue with it is just when everyone is healthy (and assuming we bring in Zubimendi), where does everyone play? But personally, I think that's a problem we need to have and it will force more rotation by Arteta.
Tell me this wouldn't cook against a lot of teams:
Martinelli - Havertz - Saka
Odegaard - Nwaneri
Rice
Then add in a pacy winger like Nico Williams/Barcola/Semenyo, a striker like Sesko/Ekitike, a DM like Zubimendi and we have a lot of flexibility and lineup options for different games/gamestates.
