What if I told you that I think he should be our #1 RB for the whole season?
He's such a weapon for us on the ball as well, always calm, has the ability to play himself out of bad situations (especially in this modern style of high press off goal kicks that teams do)and is a reliable option for Szczesny, the two CB's and Pjanic to find whenever they need to offset the ball.
As long as he has somebody like Khedira or Can on his side who can drop down as RB whenever he leaves on a run then we're good.
