RB. Arsenal. CALUM CHAMBERS. 8.0. This was the type of game that would suit Chambers when playing at right-back. Not up against a lightning-quick winger who can beat him in one-on-ones and with plenty of the ball to get forward, Chambers was excellent. Passing was very good, assisted the opening goal with a superb cross, and looked like a right-back. Even moved to left-back after Tierney’s withdrawal and did not look out of shape, as well as notching his second assist with a terrific run and cross for Nelson. He should not start there against United, but in the form he is in, he might be ready to play centre-half.
