I see no updates on his future except posturing via media from Madrid, but then again I haven't really been following this closely. Last I heard was that Perez didn't want to pay more than 50 million Euros which is a joke obviously. Other than that, nothing. That leads me to go on the last offical update, which was from the horse's mouth. Okay, he didn't say he was unhappy per se, but not many players do, just like many wont hand in a transfer request, in fear of losing various bonuses etc. Yes, I get that everything here is conjecture at the end of the day, yet we can read between the lines and try to understand what the player is thinking/feeling. It's much more likely that he still wants to leave. The fact that he made a comment 6 months ago, along with Riola, who said that he wanted to move as well, could yet be more proof that nothing has changed and he still wants to go. That's what I believe, personally.
If he does return, and start putting performances for us, then I'll have absolutely no problem in admitting that he was just injured and there was nothing untoward. Again, I hope I'm wrong, and he stays, but personally, I think he'll go. If he signs a new deal, I won't give two fecks about it to be honest, he's put in a few dreadful performances for us, but I've never questioned his attitude, so he can be as greedy as he likes so long as he largely remains the same player for us. I had no problem with Keane, Rio, Rooney and De Gea doing it. Players know their worth and good on them. So you won't find me saving face just to try to come off as I was right all along on an internet forum. Made a dick out myself plenty of times on here, so theres hardly anything left to save.
Again, to your last paragraph, I cheer for every United player, less so than I used to but I guess I just got older and got less attached to them. I do, however, want us to have the best players, the best managers, the best infrastructure and so on, in order to have the best chance to compete domestically and in Europe more so -- I always believed we should have had at least a couple more European Cups -- so of course someone of Pogba's quality would be big help on the pitch, and indeed off it -- as he would attract players himself, who'd want to play alongside him. I absolutely do not want for Pogba to leave, but if he had decided to leave, and is adamant about it -- cut him loose (with best deal possible, whether it be cash or player + cash) and use the money to rebuild. Now, I believe he that he has decided to leave. Is it conjecture -- well, of course it is, but it is a probable outcome at this point. I mean, if he had a change of heart then, we'd almost certainly would have heard by now. Yes, yes more conjecture..
