Oldham's reward for conquering Liverpool is another Merseyside test after they were drawn against Everton in the FA Cup Fifth Round.
Paul Dickov's side recorded one the biggest upsets in competition history by beating the Premier League giants 3-2 at Boundary Park on Sunday and the League One Latics have to call upon the same fighting spirit if they're to beat the Reds' Stanley Park rivals at Goodison Park.
Fellow giant killers Leeds, who dumped Tottenham out earlier in the day thanks to a Ross McCormack goal, were handed a daunting trip to Manchester City, while MK Dons' prize for thrashing QPR is a home tie against Championship struggler's Barnsley.
Non-League Luton, the lowest ranked team left in the competition after Scott Rendall scored the only goal at Norwich, will tackle Millwall after both teams knocked out top-flight opposition to reach the last 16. Meanwhile, Middlesbrough must wait to learn their next challenge after Brentford forced a replay against Chelsea following a 2-2 draw Griffin Park.
