This is not merit though, there's no mention of what it is about him as a manager that merits getting another season.
The structure will be there for anyone. What about his performance as Man Utd manager over the past few season gives us reason to believe he merits a third season? Given the tactical issues we have this season, the quite terrible records he's set as manager and considerable underperformance by several players - including those specifically recruited by him, how has this manager shown that the can build and manage a football side capable of winning the title?
Can he come out top in tactical battles with the best in the world, and when has he shown that? Can he adapt the game plan to the situation we are in, the competition we are competing for or the opposition we are playing, and when has he shown that? There are concerning performances against sides that are quite clearly and obviously less talented and have considerably less ability than us, why is that?
Another thing to keep in mind, is that his contract expires next summer, so if you intend to keep him without undermining his position as manager with a lame-duck season, you also have to consider extending his contract.
