Why not Wilshere??
Coquelin actually developed a lot that season. You can see his long balls and dribbling are actually quite good by the end of the video.
IMO he’s got more in his locker than Xhaka. He’s the only player we’ve had in years who could actually slide-tackle cleanly AND win the ball, he’s way more mobile and agile than Xhaka, he’s long passing isn’t as good perhaps but it’s still good, he can dribble way better than Xhaka, he’s way faster than Xhaka.
I think he deserves another chance in the line-up playing next to someone like Wilshere because he was genuinely awesome for us with Cazorla.
