Even if Man United sign Cesc or Nagelsmann, they will still need a couple of years to reach the level required to challenge for titles. People compare us to them, but Chelsea already had that structure; however, internal issues and Maresca wrecked our season. The structure is already there but needed fine-tuning to add athleticism, experience, and a bit of physicality, which Alonso has done. The structure and the foundation are already there. Alonso's job is to finish the house. For Man United, they are yet to buy land, let alone build a foundation. They have to start from scratch.
