Burnwinter Getting that feeling too. Nothing much to go on but I think Arteta would be willing to fight tooth and nail to not lose Myles or Dowman, and I'm not getting that feeling about Nwaneri at the moment.
The fans have this idea that Madueke is taking minutes from Nwaneri, but I think Arteta is looking at Dowman right now and wonders what Ethan contributes with that Max can't over the next 12 months. When you're no longer the hottest talent on the block you need to keep your head down a bit and show you're willing to put in the hard work.
From what's being reported I don't think Ethan, rightly or wrongly, has done that to a degree that has satisfied Arteta. And the fault might very well be Arteta's too: he hasn't really shown so far that he has the soft qualities you need to develop these pampered youth players. What he has shown is low patience with players who don't exhibit the correct character and attitude right from the start though.
