Both sides kept just two players from the teams they fielded at the weekend, a familiar theme on the night with the 12 teams in six matches collectively making a total of 99 changes. Holder Manchester United made eight changes to the side humbled by Huddersfield Town on Saturday but were too strong for Swansea City with Jesse Lingard scoring both goals in a 2-0 win. Arsenal manager Arsene Wenger even put out an entirely new starting XI from that which faced Everton on Sunday and had substitute Eddie Nketiah to thank for the 2-1 extra-time win over another second-tier side Norwich City.#CarabaoCup: Tuesday night's Round Four results ? pic.twitter.com/HeSxyrypGR

The 18-year-old scored twice - his first goals for the club - including one with his first touch 15 seconds after coming on in the 85th minute. The goal was the first scored by an Arsenal player born after the Frenchman took over as manager. Nketiah added his second six minutes into extra time as Arsenal, who had trailed to Josh Murphy's 34th-minute opener, finally saw off the spirited challenge of the visitor."We were always in control. I'm pleased with the performances of the team and individuals." More from the boss: https://t.co/OF55ertS2N pic.twitter.com/1Hv55OTF4S

Bristol City inflicted more misery on Premier League basement side Crystal Palace and former England manager Roy Hodgson by routing the south London side 4-1 at Ashton Gate. Hodgson endured an ill-fated spell in charge in Bristol in 1982 and had an equally chastening night on his return 35 years later as Bristol claimed their third top-flight scalp of the season to reach the last eight for the first time since 1989. Leicester City caretaker manager Michael Appleton made it two wins from two as his Midlands side came from behind to beat Leeds United 3-1 with goals from Kelechi Iheanacho, his first for the Foxes, Islam Slimani and Riyad Mahrez.The first team to stop Manchester City scoring in 90 minutes this season...
