They're not unplayable in one off games but over the long grind of a season we don't have the squad depth to be at the level we need to be week in week out. That can be improved but not to City's level. That's where over the course of a season they're likely to do better. If we get close enough though then it could come down to a few games here and there though so I guess we'd have a chance as Utd showed this year.
