The Liverpool-Manchester United Premier League game on October 15 has hardly been out of the headlines since Manchester United defender Patrice Evra accused Liverpool's Uruguayan striker Luis Suarez of racially abusing him during the game.
Although Suarez denied the charge, the FA found him guilty, banned him for eight matches and fined him 40,000 pounds.
He will still be serving his suspension when the match is played at Anfield on the weekend of January 28-29, but will be available to play against United in the return Premier League match at Old Trafford on February 11
The draw bringing Liverpool and United together also comes two days after a 20-year-old Liverpool man was arrested and charged with alleged racist abuse towards Oldham Athletic's Tom Adeyemi during Liverpool's 5-1 third round win on Friday.
Sunday's draw also raised the possibility of a quick rematch between Chelsea and Queens Park Rangers, provided QPR win their replay against League One Milton Keynes Dons.
Emotions have run high between the clubs since they met at Loftus Road on October 23 when Chelsea skipper John Terry was alleged to have racially insulted QPR defender Anton Ferdinand.
Terry has strenuously denied the allegations, but has been charged by the Government's prosecution service and will appear in court to face the charge on February 1, three or four days after their possible cup meeting with QPR.
WARNOCK SACKED
United knocked out holders Manchester City on Sunday after winning a thrilling third round tie 3-2 after being 3-0 ahead at half-time.
Apart from the controversy surrounding the Liverpool game, they now face another tough match against one of the Premier League's top teams.
United, who have won the FA Cup a record 11 times, have beaten Liverpool twice in the final itself in 1977 and 1996 but Liverpool won their last meeting in the competition, a 1-0 victory in the fourth round in 2006.
United striker Wayne Rooney, who scored twice in the victory over City and started his career at Everton, was relishing the trip to Anfield.
He said on Twitter: "What a draw for [the] next round. Another big game. Can't wait for it already."
United's former Liverpool striker Michael Owen said: "And people talk about United always getting lucky cup draws! It couldn't get much tougher. What a game to look forward to."
Chelsea, who won the FA Cup three times in four seasons between 2007 and 2010, lost their League match 1-0 against QPR on October 23 but QPR's form has slumped significantly since then and Chelsea will be favourites to advance.
If they do face QPR, a different manager will be in the home dugout after the West Londoners sacked manager Neil Warnock on Sunday following their slide down the table.
Tottenham Hotspur, eight times FA Cup winners and the highest ranked team left in the FA Cup behind United, make the short trip to Championship
