FA Cup - Man Utd draw Liverpool in FA Cup
United, who dumped out the holders Manchester City 3-2 in an explosive derby earlier in the day, are rewarded with another trip to one of their bitter rivals in three weeks time.
Relations between the two clubs have been strained since an incident in which Liverpool's Luis Suarez was found guilty of abusing Patrice Evra during a Premier League match between the two sides. After an FA hearing, Suarez was banned for eight games. The Uruguayan will still be serving his suspension when the tie takes place.
All-Premier League ties see Everton host Fulham and West Brom take on Norwich, while QPR will entertain Chelsea if they beat MK Dons in a third round replay, while Arsenal will host Aston Villa if they can defeat Leeds United in Monday night's fixture.
The ties will be played over the weekend of January 28 and 29.
