You need 3 things to be able to turn the corner from mediocrity.
1. Owners willing to spend
2. Director of football who knows how to spend
3. Manager who's able to assess the talent and use it properly
United currently has none of the above. Arsenal has a DoF, owners spent money this window and Emery is Emery.
I'll give you the last two, but how can you say the Glazers/Woodward aren't willing to spend when they dropped 145 Million on three players this window? They just happen to be idiots that don't know what they're doing with the money.
Ceballos has been good for us over the past two games, but he needs to understand that you can't play with the ball in the final third like that against Liverpool. It'll hurt you badly if you do it enough times. And will somebody do something about the right wing/channel? Arsenal's getting destroyed out there.
