United have their noses in front at half-time of an absorbing derby. City started like a house on fire, pulling United's defence apart and taking the lead with Sergio Aguero's first goal in seven games.
United were on the ropes for a period but fought back brilliantly. Their first meaningful attack created Ashley Young's equaliser and they then grew into the match, taking the lead with a classic Fellaini back post header.
City are still a big threat in this game. United's high defensive line looks vulnerable to their pacy counter attack. There's a long way to go yet in this game.
