I get the argument for moving Martinelli on due to his value. Don't agree, but get it.
I love the chaos Martinelli brings. I love that he's not a typical Arteta player and that he brings a different type of excitement to the likes of Saka and Odegaard.
He's had a relatively easy ride though. For a few years he hasn't really had any real competition or risk of being benched. He could benefit from being clear second choice with incentive to improve as just now it feels like a coin toss whether it'll be him or Trossard who start. Progress isn't linear and it may be the making of him. It may not be, and it's a fair viewpoint to take that you may not necessarily want someone who doesn't have an innate desire to improve anyway.
The better option to me now is selling Trossard and/Jesus and replacing them with a clear first team upgrade, and relegating Martinelli into a backup role with incentive to develop and regain first team minutes. He's past the needing minutes to develop stage - he needs time to work on the aspects of his game that need improvement if he's going to progress, and that's part mental part training time. Being backup might give him that time he needs to reassess and kick on. If that doesn't work out we can still move him on and his value isn't going to diminish that much in 1/2 years. The alternative is we let him go to bring in someone who isn't guaranteed to be an improvement, at least in the short term, and still have Trossard/Jesus hanging around. That's just frankly not appealing in any way.
