Man Utd's forgotten defeat that made Man City's iconic Sergio Aguero moment possible

When we talk about the 2011-12 Premier League title race, it's hard to look beyond the final day drama where Sergio Aguero delivered Manchester City their first Premier League title in stoppage time.

However, a few weeks before those events, Manchester United had what looked like an unassailable lead. A big shift happened in the middle, though, and it started with a short trip to Wigan to face Roberto Martinez's relegation-fighting Latics.
