All players can tell their managers where they would like to play and then it's up to the manager. The more indulgent the manager is towards the player then the more chance they will play the player where he wants, and both Van Gaal and Hodgson were incredibly indulgent towards Rooney.
That's hypothetical though. All I'm trying to do is determine why you are so sure this is good news for Rooney. You keep saying he wants to play upfront even though everyone is quoting Rooney saying he is happy in midfield and sees his future there. You also denied that Rooney has been talking himself up as a midfielder when Rooney has said his midfield game is a mixture of his own abilities plus what he has learned from Gerrard and Scholes... And you are ignoring the point that Mourinho has said he wants to play him in the positions that two of his new signings can also play.
It comes across as you simply being determined to see everything as a positive for a player you like. Consider this; if Mourinho has said the exact opposite of what he said today, something along the lines of "Rooney will play in midfield for me. His attributes, especially his passing under pressure, are well suited for that role," then I would have posted that the press conference was great for Rooney. It would have shown that his new manager was impressed with his performances at the end of last season and over the summer and agreed with Rooney's own recent statements. Are you honestly telling me if Mourinho had said that today you would have posted that it was bad news for Rooney? If no then how can the reverse be a positive for him?
I think some people are forgetting that naturally, Rooney is a striker/support striker. Therefore, if given the chance to play, which he wasn't always been the case in the last couple of years, then of course he's going to like it. Why wouldn't he?
As for Rooney supposedly talking himself up, well, when the media continue to ask him if he sees himself as a midfielder, especially when he's doing well in that position, then he's going to say yes, especially if the manager who's there at the time is playing him there.
One thing about Rooney is, he's always been very unselfish, and this is a big reason he gets moved about. Wing, up top, 10, 8, etc. He's a versatile player, who always will, and always has, 'done a job' for the team, but that's not to say he doesn't want to play in his preferred role. (9 or 10)
As for the two signings, Mourinho clearly pointed out that he 'made a nucleus of four signings'. It doesn't take a genius to know what positions needed strengthening. Most people were suggesting we should sign a striker, a right winger, a centre back and a centre midfielder before Jose was even announced.
If Mourinho always had it in his head that he would play Rooney as a 10 - the position that most put him in for predicted XI, then technically, Mourinho hasn't signed two players who play the same position. Yes, Mkhitaryan can play attacking midfielder, and Rooney can play 9 like Ibra, but Mourinho specifically stated that he wants specialists, and most of the time, I can imagine these three players will play together. Therefore, the only way Jose will fit them in is by playing a front four of:
Ibrahimovic
Martial Rooney Mkhitaryan
And the last bit is nonsense, in my opinion. You are looking at the last say 2-3 months, in comparison to the duration of Rooney's career, where he has played as a 9 or 10.
I think people are getting confused with Mourinho's comments. It's not a fact of Mourinho doesn't like Rooney in midfield, but more that he feels he can do a much better job, and is more of a threat in closer to goal. He said "the natural appetite to put the ball in the net never changes." Mourinho know's that, and has taken that into account. The guys nearly our top goalscorer, for God sake.
