The guy can't and won't be here next season. It would be twice the mistake retaining Ten Hag was for United, and I would argue the Dutchman was more popular with the fans than Postecoglou is with our fans.
I do not doubt the guy's credentials in being given the job but I also think it is fair to conclude that is an ask too far.
No personal gripe with the bloke, as I don't know him, but as a Spurs fan, you can't derive comfort in being nearly certain you are going to lose to the likes of Fulham and Bournemouth, pretty much regardless of the overriding circumstances.
