How is he trying to accommodate Pepe? Arteta is accommodating everyone but Pepe.
Xhaka is playing in his preferred position and drops into left back so he can't be pressed.
Özil is playing as a 10 with complete freedom even though he has no offensive or defensive output.
Auba has the freedom to move inside off the flank and Bellerin is being tucked in to form an extra midfielder to protect our slow midfielders on the counter.
Pepe is on the right hand side, with no help and is so far away from goal he has to beat 2 players to even play a simple pass. If there is anyone we are no accommodating it is Pepe.
He's accomodating Pepe by allowing him to play his natural game, that is to try and beat opposition fullbacks like a winger of his type does. Bellerin's deeper role allows for recovery in case Pepe loses the ball.
If Arteta was to play the way he wants there'd be a hard working player who cuts inside and overloads the opposition defence, or supports the midfield like an inverted winger does, and Bellerin would be able to overlap. But that's not Pepe's style.
