Don Pacifico I think that's based on hope more than anything at this point. I'm on record as loving Martinelli and his chaos aura, but feel this season is make or break for him. He doesn't have the luxury of youth and naivety any more.
Sterling is his biggest danger. Sterling won't be a long (or even possibly medium) term option, but he could show Arteta what he is missing in that position in terms of output.
It'll be interesting to see how Sterling plays out. He's not got the legs of Martinelli or Saka so you'd think there will be a few tactical tweaks to accommodate that which we may not have seen yet from Arteta. I hope we end up with one or both wide players doing less running and staying higher as a result.
We also need to fit Timber, Calafiori and Merino into that set up. I'm not convinced this team has the same peak as last season.
