Navratilova's was probably the greatest achievement, in that it took months to achieve (although you could argue that all of these moments took a lifetime to get to where they did), but as far as moments go, that Aguero goal was the pinnacle of Premier League entertainment. What makes it doubly remarkable, was that Man City were losing 2-1 just 2 minutes before that and they needed to win to win the league. An absolutely ridiculous end to the season.
