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.
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.
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.
Apart from the controversy surrounding the Liverpool game, they now face another tough match against one of the Premier League's top teams.
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.
