Peterborough 1 - 5 LeicesterThe air went out of this tie quickly. Fousseni Diabate gave Leicester a fast start with a neat, prodded finish before, three minutes later, Kelechi Iheanacho curled a low shot beyond Jonathan Bond to make it two. Iheanacho would add a third inside half-an-hour, effectively ending the contest and even with Andrew Hughes grabbing a consolation shortly into the second-half, Diabate would add his second of the game late on to restore some gloss to the scoreline and, in injury-time, Wilfred Ndidi scored a fifth.Goals: Hughes 58' - Diabate 9', Iheanacho 12', 29', Ndidi 90'Huddersfield 1 - 1 BirminghamSteve Mounie gave David Wagner's side a first-half lead, meeting Florent Hadergjonaj's header perfectly to beat David Stockdale in the visiting goal. Birmingham would level the game shortly after half-time, with Lukas Jutkiewicz finishing well after a mistake by Michael Hefele and that would end the scoring - replay needed.Goals: Mounie 21' - Jutkiewicz 54'Middlesbrough 0 - 1 BrightonNot a classic and few signs that Brighton are properly invested in this competition - Chris Hughton made all sorts of changes to his starting eleven, fielding a virtually unrecognised defence and a makeshift attack. Middlesbrough didn't take advantage though and, with almost the final kick of the game, the ball ricocheted off Glenn Murray and in. Brighton through to the next round.Goals: Murray 90'Notts County 1 - 1 SwanseaA turgid game throughout most of first-half, but Luciano Narsingh put Swansea ahead in stoppage time. The visitors had deserved their lead - just - but wasted little time in surrendering it, with Jon Stead (remember him) equalising from close range at the beginning of the second-half. Back to the Liberty Stadium they'll have to go - another replay needed here.Goals: Stead 62' - Narsingh 45'Southampton 1 - 0 WatfordNot quite the start that Javi Gracia had in mind, with Jack Stephens giving Southampton the lead within four minutes after a Shane Long shot had deflected to him. Watford huffed and puffed but with little effect and Southampton are through, gaining a modicum of revenge for what happened in the league game two weeks ago.Goals: Stephens 4'Wigan 2 - 0 West HamWill Grigg opened the scoring here, thudding a header past Joe Hart ("...your defence is terrified..." etc). It was a lead which Wigan would take into the break and it got worse for West Ham soon after the restart, when Arthur Masuaka was shown a straight red card for spitting at Nick Powell. West Ham were condemned to an embarrassing exist on 62 minutes, when Grigg doubled his side's lead and his own tally, converting a penalty harshly awarded for handball. Laughably poor from the visitors.Goals: Grigg 7', 62 (pen)Other results:Hull 2 - 1 Nottingham ForestMillwall 2 - 2 RochdaleMK Dons 0 - 1 CoventrySheffield United 1 - 0 PrestonYeovil Town 0 - 4 Manchester United (Friday)
