Wenger's done enough to warrant another year imo.
Had Klopp left a year ago, Arsenal fans would have been clamouring for his immediate appointment. Wenger has enjoyed a growth in stature and are by far and away the form team in the PL. If you make it nine wins on the bounce at the expense of Chelsea, and reach another FA Cup final, he's had one of the best seasons of his last decade despite the disappointingly early CL exit.
He'll see out his deal until 2017. I'm sure of that.
