Lol, Rooney is going nowhere. He has outlasted a lot of strikers at OT, his stats are getting better; assists, chances created, goals etc. He is the best all round player in the premier league. Sure there are better strikers than him, and better wingers and num 10s, and better technical players, but he can play all those positions in a more-than-average rating. In UTD, he is the one player you can slot into any of the forward position and even the midfield. And like it or not, as a number 10, currently for UTD, he is better than Kagawa. He is the only one we have who can gel with any striking formation or partnership: See Rooney-RVP, Rooney-Chicha, Rooney-Welbeck, Rooney-Kagawa. And for that last one you just have to look at our last premier league game. Now mix those partnerships up and look for games where they were used and then you begin to see how good he has been for us. Sure he is not the most technically gifted player and he has a terrible first touch, but he can adjust to any player and is extremely intelligent, especially in the final third plays. While he may not always be consistent he has been our most consistent palyer over the last 5-6 years.
If I can see these values in him then I am sure the manager sees it too.
