Here are the top five statistics from the weekend encounter:
1) Saturday’s match versus West Ham is the first time Wayne Rooney has been sent off for five years; since March 2009 in an away tie at Craven Cottage against Fulham.
2) Rooney's opening goal in this tie took him to 176 in Premier League history, one more than Arsenal fan favourite Thierry Henry (175). The England captain has now scored seven goals in his last five Premier League games at Old Trafford.
3) Robin van Persie has now scored 70 goals in the Premier League in the last four seasons, more than any player. The Dutchman is only the second non-British player (after Dwight Yorke) to score 40-plus English top flight goals for two different clubs.
4) Radamel Falcao has recorded a greater number of assists in his last two Premier League games (2) than he managed in the last three domestic seasons combined (1).
5) Saturday’s tie saw Rooney and van Persie score in the same top flight game for the first time since February, versus Crystal Palace.
