At home to Forest on match day one? I'd start:
Ramsdale
Timber Saliba Gabriel Zinchenko
Rice
Ødegaard Havertz
Saka Trossard Martinelli
Give the new boys a chance to impress, remind Havertz he's expected to defend, and let's try out dual inverting fullbacks. The above should be a highly press resistant XL with significant defensive weaknesses, but extraordinarily rich going forward.
White, Partey and Jesus know their roles better and can be saved for bigger fish.
goon I'm quite relaxed about XIs and I think we'll see quite a few combinations this season depending on opposition etc.
Feels to me like maybe the first time ever the Arsenal squad's so thick the players won't really be able to maintain that being benched is a major insult. Likewise I think there's enough talent and intelligence there for several variations to be used through the season—if Arteta's got the head for it.
