United replied immediately through Rooney, and Louis Saha finished the game off in the final minute with what turned out to be the French player's final goal for the club before being sold to Everton in the summer. The Premier League's top three kicked off simultaneously on 1 March. United were first off the mark, as Owen Hargreaves scored his first competitive goal in a Manchester United shirt to put the Reds 1–0 up against Fulham. Chelsea then went 3–0 up against West Ham in the space of five minutes, before Arsenal went 1–0 down to Aston Villa via a Philippe Senderos own goal.

United goalkeeper Ben Foster, making his debut due to the unavailability of Van der Sar and Tomasz Kuszczak, then staked his claim to the number 1 jersey with a pair of fine saves from Derby striker Kenny Miller. Cristiano Ronaldo proved to be the thorn in Derby's side on a number of occasions, testing former Manchester United goalkeeper Roy Carroll with a curling effort hit with the outside of his foot and a 40-yard free kick. The breakthrough finally came in the 76th minute, Ronaldo scoring a deserved goal from a Wayne Rooney
