Man U has been intense, chaotic and full of running in their three games under Rangnick. Their game is lacking control, cohesion and creativity. Even though we expect steady improvement under Rangnick the suitability and adaptivity of the players to his style is vitally important. Lastly, Rangnick has to develop the courage to drop big name players if they're not playing well. Ronaldo was totally out of sync against Norwich. I would've subbed him after 60 minutes of the game.
