Manchester City won comfortably at Aston Villa in the fourth round of the FA Cup, while Crystal Palace progressed past Stoke City.
Arsenal beat Burnley to move into the last 16, along with Bournemouth and Watford, but West Bromwich Albion face a replay a Peterborough United.
In the day’s early clash, Tottenham Hoptspur outplayed Colchester United, and a full report for that game can be found on this site’s soccer page.
Kelechi Iheanacho struck a hat-trick as Man City won 4-0 away to Aston Villa.
Iheanacho opened the scoring early on, netting from close range after Villa had failed to clear a Fabian Delph corner that had been helped on by Bacary Sagna.
A foul by Leoandro Bacuna on Raheem Sterling midway through the first half allowed Iheanacho to coolly slide in his and City's second from the penalty spot.
Iheanacho completed his hat-trick with a little over 15 minutes of the clash remaining, collecting Micah Richards's poor back-pass and firing past Brad Guzan.
Almost immediately after the Nigerian's third, Sterling grabbed the away side's fourth and final goal by smashing home a finish when the struggling Villa defence was again unable to clear the ball from the danger area, with Iheanacho again heavily involved.
Crystal Palace booked a spot in the fifth round with a 1-0 win over Stoke at Selhurst Park.
Wilfried Zaha scored the only goal of the game, shooting through the legs of Jakob Haugaard after being found by Yohan Cabaye and powering through the centre of the Stoke back-line.
Xherdan Shaqiri missed Stoke's best chance, curling his strike from 12 yards too high.
The visitors pushed hard for a leveller late on but Palace held out to secure progress.
Odion Ighalo netted late as the Championship's Nottingham Forest lost 1-0 at home to Watford.
The Premier League men were unlucky not to be awarded a first-half penalty when David Vaughan appeared to foul Nordin Amrabat, although Forest's Jamie Ward probably had the best chance of the goalless period.
Home goalkeeper Dorus de Vries twice denied Amrabat during the third quarter.
Forest became more of an attacking threat towards the end of the encounter but were hit by Ighalo 89th-minute strike from close range, following Kelvin Wilson's mistake from an Allan Nyom delivery.
Substitute Nelson Oliveira had an opportunity to book a replay but was denied by new Hornet Costel Pantilimon.
Arsenal edged to a 2-1 win over Championship side Burnley in Setanta Ireland's live game, and the full report for this match can be found on elsewhere on our website.
Calum Chambers curled in a fine opener with the outside of his right foot after being fed on the overlap by Alexis Sanchez.
Against the run of play, Burnley grabbed a shock equaliser, as Sam Vokes headed powerfully past David Ospina from Tendayi Darikwa's cross.
Burnley went close twice early in the second period before the Gunners regained the lead when Sanchez powered Alex Oxlade-Chamberlain's pull-back past Tom Heaton.
The visitors threw everything at the Gunners late on, with Andre Gray having the best opportunity, but Arsenal held on to secure what was overall a deserved victory.
Portsmouth allowed a lead to slip in losing 2-1 at home to the Premier League’s Bournemouth.
The League Two side led at the break thanks to Gary Roberts, who shot to the bottom corner after collecting Marc McNulty's low delivery.
With Pompey on top, Roberts wasted a fine chance to double the hosts' lead, before Bournemouth equalised when Eunan O'Kane's cross was headed home by Josh King.
With both sides threatening, it was the Premier League stars who bagged the decisive goal, as substitute Marc Pugh's header deflected in off Adam Webster.
West Brom were held to a 2-2 draw by third-tier Peterborough at The Hawthorns.
The hosts moved ahead during the opening quarter through Saido Berahino, who fired in Rickie Lambert's pass from the edge of the box.
Peterborough, though, remained well in the clash throughout, equalising with just over 10 minutes remaining when Shaquile Coulthirst benefitted from confusion between Sebastien Pocognoli and Boaz Myhill to find the bottom corner.
The Baggies restored their lead through Berahino's finish from a tight angle following Craig Dawson's cross, but Jon Taylor earned a replay for the underdogs by firing in from the edge of the area.
