I've just watched Postecoglou's post-match press conference. He let the mask slip there, didn't he?
Okay, he's understandably in disagreement with anyone who wanted Spurs to lose last night, and that pissed him off, but I sense that it's not the entire picture. Conflicts behind the scenes would be my guess, possibly brought to a head by the win/lose debate.
He came very close to losing it and showing his 'Mr Angry' side, which is why he had to walk out of the presser.
It looks to me like there's a battle of wills going on behind the scenes, with Ange's position being 'My Way or No Way'. Who's not fully onboard with him? No idea, but the Summer will be interesting, one way or another. I don't think we'll be starting next season as a 'carry-on' film - changes are afooooooot.
