I only half agree, as you say elsewhere in that post Nwaneri has pace and Trossard's also capable of a breakaway, the odd occasion in recent games someone's played a searching ball forward it's often led to a good chance or a goal
And in any case it's the way we always play even with Martinelli, Saka (who admittedly I'm not sure is as good on the break tbh but then we never get the chance to see it really) and Havertz
There's a lack of willingness to try anything risky and i think it's the stranglehold Arteta has placed on players
