They're pre-scheduled, it came out on the dot at half past the hour or something. They won't actually put them out live.
It would have been put out by his PR people, you don't think they know exactly what's going on and how it would be interpreted? They could have pulled it before it went out. They knew it was going out and they knew how it would be read.
Anyway, that's just a small part of the overall point being discussed. I personally don't think you can argue that the players stopped playing for him. Utd were regularly dropping points in games where, no matter the set-up either from them or the opposition, they shouldn't have been. The question isn't whether the players stopped playing for the manager but how much was that down to Mourinho's own doing and imo the vast majority of the blame lays at Mourinho's door. How can you get players to go that extra mile for you when you're constantly putting them down, blaming them for loses but taking any glory for yourself?
edit: just quickly on Pogba, he's clearly played the PR game as much as Mourinho has. He's came out with his comments in the past few months knowing they'd cause trouble. Liverpool do a tunnel cam/behind the scenes thing for every home game and after the Utd game Pogba was stood right in front of the camera congratulating every Liverpool player as they left the pitch. Maybe he was just being a really good sportsman but I'm not sure you'll find many players doing that when you've lost to your biggest rival and I got the impression he was doing it for the camera.
