The sack, OBVIOUSLY.
WTF? AVB has got a 100% record in Europe with Tottenham (apparently - I read somewhere), a 52.9% Premiership win rate with Tottenham - the best of any Tottenham Premiership manager and they're 7th in the Premiership... So what do you do with him? Sack him.
Well alright, 7th is wank, when you consistently come less than 4th, but it's still pretty good considering what's going on this season. What more can any competent manager do. You get the most expensive player on the planet sold from under your feet for an 9 digit telephone number (what was it? £084560000?). A couple of duff results in succession - one against the second best team in the league - and it's curtains. Go figure.
I've actually worked under contract for one of Levy's companies 25 years ago and I can't for the life of me recall getting paid. My memory ain't what it used to be though, so maybe I did. Levy's hard as nails, no doubt at all.
