My thoughts too - i thought he'd give Laca 20 minutes to try and keep him happy but Wenger doesn't do that.
Instead he's doing to Laca what he did to Perez - put him in with players who don't give him the ball in the right places and then implying it's all his fault by dropping him
In Laca's case it's all the more ironic as replacing ball-losing Sanchez with team-player Mika there will more opportunities - only they will now fall to Auba
