Rooney and Ronaldo were world beaters at his age now, and not only is he miles off from reaching 24 year old Ronaldo/Rooney levels, but he seems to be on a steep decline if the last 18 months are anything to go by.
I'd honestly pocket a healthy £40million for him instead of feeling compelled to give him a new contract that takes him to his late 20s, after which we'll struggle to offload him to the Palaces and Evertons.
I remember when PSG offered us £40million for Januzaj years ago, with the benefit of hindsight we're probably kicking ourselves that we didn't accept, but at the time it was unanimously rejected by the fanbase because he was considered our future posterboy.
