I've seen Eddie benched after scoring goals too. Arteta clearly wants something which he believes Eddie will give which Laca cannot. Also we seen Laca's reaction vs Liverpool, he has a tendency to lose confidence really easy and really stink the place up, maybe Arteta's knows what's coming. It sometimes takes months for Laca to recover.
Didn’t seem low on confidence when he stuck his penalty away against Liverpool I. The league cup. There’s a distinct lack of goals in this team and Laca is 3 in 3. He should’ve started. (Of course Eddie will score now I’ve said this.)
