Timber, by contrast, is not lacking for sharpness or playing time. On the contrary, it is something of a miracle that the Dutchman has played as much as he has this season, given he missed almost the whole of last term with a torn ACL. But if he is not risked either, then Thomas Partey will almost certainly have to play at right-back, with a knock-on effect on how far Arteta can rest or rotate in midfield.
