You're wrong, no?
Fine, and what about stronger sides? You wanna play Havertz or Jorginho? They don't have the engine either so not really sure what you want to see there.Against weaker sides you probably could get away with Trossard at LCM.
He is good but he does lack a bit of engine / physicality which would concern me.
Arteta messed it up in the summer, and he needs to work with what we have now. Saying Trossard shouldn't play doesn't add anything knowing that other options are so much worse
