Gillingham send Cardiff crashing out the FA Cup
Cardiff will have more time to focus on Premier League survival after they were knocked out of the FA Cup at Sky Bet League One outfit Gillingham.
The Gills, 19th in the third tier, have their own relegation battle to contend with, but they overcame odds of 18-5 to stun Cardiff with a 1-0 third-round victory courtesy of an 81st-minute goal from Elliott List.
Cardiff's relegation rivals Huddersfield lost to Championship opponents Bristol City and Crystal Palace made hard work of their 1-0 win over ten-man League Two outfit Grimsby.
Palace were 1-50 to win the game after the Mariners had Andrew Fox sent off in the second minute but they traded at 6-4 before Jordan Ayew's late winner.
Manchester United made it five wins out of five under interim manager Ole Gunnar Solskjaer thanks to a 2-0 victory over Championship strugglers Reading.
The Red Devils were backed from 1-8 into 1-12 before kick-off but it wasn't a vintage performances from the hosts, who progress to the fourth round thanks to a Juan Mata penalty and a strike from Romelu Lukaku.
Joe Willock sent Arsenal on their way to a 3-0 win at Blackpool with a first-half brace. The teenager was an 11-1 chance to score first.
Southampton traded at 1-33 in-play after Nathan Redmond's brace put them 2-0 up at Derby but the Rams rallied to earn a replay at St Mary's.
Ipswich, bottom of the Championship, lost 1-0 at League One Accrington although it wasn't much of a shock in betting terms as Stanley were 13-8 favourites.
Everton were unconvincing 2-1 winners at home to Sky Bet League Two leaders Lincoln, while Swansea won 3-0 at Aston Villa and Middlesbrough crushed Peterborough 5-0.
Two goals from Alvaro Morata gave Chelsea a 2-0 victory over Nottingham Forest while Brighton won 3-1 at Bournemouth in an all-Premier League clash and West Ham saw off Birmingham 2-0 with goals from Marko Arnautovic and Andy Carroll.
