Mourinho almost won the league with an aged and already declined Eto'o plus Torres and Ba a couple of seasons ago when he desperately wanted to sign Rooney from us. He probably would have gone all the way too, if Chelsea hadn't been robbed in the game against Sunderland. Nevertheless, he got them very close to winning the league with limited options up front. I guess that Rooney, even now, is in better shape and can be more reliable than the choices Jose had back then.
Maybe Mourinho can figure out a way to play him up front (or behind the lone forward) without affecting the overall quality of the first xi. I'm saying that because, as many have pointed out, it's difficult to ditch him while he's on his current contract. This, of course, means that Mourinho will have to sort out the rest of the team, create a formidable defense and fill the midfield with runners (on and off the ball) and players who can be productive on both ends of the pitch.
We can blame LvG for many things but i believe that the notion that Rooney's future lies in a midfield role is truly the worst thing he can leave behind when he leaves the club. Given Rooney's presence in the dressing room and the fact that he has a lot of friends in the press, this could turn into a real problem for LvG's successor, whoever that may be.
Ferguson made the decision to make Rooney a second striker because he believed that he wasn't the man he could rely upon for 20+ goals per season. On the other hand he believed that Rooney's best traits, his work rate-his tendency to chase second balls in the attacking half and his ability to create pockets of space for others or spot late runs in the box, could prove useful, if he was utilized in the hole. These traits have nothing to do with all the great attacking midfielders of the past who were successfully converted into midfielders in deeper roles. Those were players who could dictate tempo, who could run with the ball through the lines and had an exquisite passing range.
Whenever you play Rooney in the midfield, you still get a forward in a deeper role. You get the nerves, the -full of risks- decision making, the frantic positioning and the enthusiasm to chase the ball all over the pitch... abilities that can prove quite useful in an attacking role but, unfortunately, they don't make a good midfielder.
LvG is acting like Pontius Pilate in this matter. He doesn't want to make Rooney angry and he surely senses that this may not be his problem anymore in three games time. After all, if he truly wanted a risk taker in that role, he had Herrera, who is actually a midfielder, for that role. But he knows that he's hanging by a thread for quite some time now and therefore he's doing whatever he can to please his captain.
