Aside from the Reds' FA Cup mugging at the hands of Portsmouth, United won six Premier League and Champions League games in March without conceding.
Fulham, Lyon, Derby, Bolton, Liverpool and Aston Villa were all put to the sword - but who was the Reds' star man in March, in your opinion?
Cristiano Ronaldo bagged seven goals in six appearances, including yet another superb free kick in the Reds' 2-0 victory over Bolton at Old Trafford.
It took Wayne Rooney until the final game of March, against Aston Villa, to get off the goalscoring mark with a fine brace, but his all-round play was exceptional all month long.
Carlos Tevez ended his own goal drought against the Villans, but his unwavering commitment and classy support play was key as the Reds tore their opponents to shreds.
Paul Scholes and Michael Carrick also shone, lending their fine support in attack and defence, and generally bossing games in which they featured.
In defence, Rio Ferdinand again came to the fore in the biggest matches, with a particularly classy display against Liverpool, while Wes Brown chipped in with a rare goal against Rafa Benitez's side to cap a string of fine displays.
