Teenage striker Eddie Nketiah came off the bench to score twice on his home debut and send Arsenal into the quarter-finals of the Carabao Cup at the expense of Norwich.
The England Under-19 international had played just a minute of first-team football for the Gunners before his introduction saw Arsenal come from behind and win 2-1 after extra-time.
Josh Murphy put Norwich ahead with a deft chip, his fourth goal in the competition this season, but the Canaries were guilty of wasting a host of chances to kill off the tie.
Nketiah, 18, then equalised with his first professional goal just 15 seconds after coming off the bench.
That sent the tie into extra-time, where Nketiah headed home to seal a memorable Emirates Stadium debut and put Arsene Wenger’s side into Wednesday’s quarter-final draw.
Swansea City 0-2 Manchester United
Manchester United bounced back from their Huddersfield horror show with a comfortable Carabao Cup victory at Swansea.
Jesse Lingard’s first United brace secured a routine 2-0 win as the competition holders made safe progress into the quarter-finals.
It was just what United needed after the shock of their first Premier League defeat of the season at Huddersfield on Saturday.
But Swansea, just as they had been in losing 4-0 to United at the Liberty Stadium in August, were accommodating hosts and provided little contradiction to the belief that a long season lies ahead of them.
United boss Jose Mourinho said after victory over Burton in the previous round that they would be better off without this competition on their itinerary, suggesting they would be fresher for Europe.
Bristol City 4-1 Crystal Palace
Bristol City claimed a third successive Premier League scalp as they moved effortlessly into the Carabao Cup quarter-finals at Ashton Gate.
After knocking out Watford and then Stoke, the Sky Bet Championship club saw off top-flight strugglers Crystal Palace after first-half goals from Matty Taylor and Milan Djuric sent them on the their way to a 4-1 win.
Palace led through a Bakary Sako strike, but City never looked back after going ahead, and Joe Bryan’s rasping left-foot shot on the hour confirmed Palace’s fate in front of a 22,000 crowd, before Callum O’Dowda underlined it six minutes later.
It is the first time since 1988-89 that City have reached the League Cup quarter-finals – they were beaten on aggregate by semi-final opponents Nottingham Forest that season – as Lee Johnson’s team marched on.
Palace, bottom of the Premier League with just one win from nine games, did not help themselves in defence, but City’s greater finesse in front of goal deservedly reaped its reward as the Robins romped home.
Manchester City 0-0 Wolverhampton Wanderers (4-1 on penalties – AET)
Claudio Bravo was the hero as stuttering Manchester City needed penalties to see off hard-working Wolves and make the Carabao Cup quarter-finals.
Pep Guardiola’s Premier League leaders hosted Nuno Espirito Santo’s Sky Bet Championship table-toppers in a match that promised much but failed to deliver goals over 120 minutes.
Often-maligned Bravo saved City’s blushes on several occasions during the match and proved the spot-kick hero, denying Alfred N’Diaye and Conor Coady as the hosts won the penalty shootout 4-1 after the game ended 0-0.
Bournemouth 3-1 Middlesbrough
Callum Wilson ended his nine-month injury nightmare with a match-winning display as Bournemouth booked a place in the Carabao Cup quarter-finals with a 3-1 victory over Middlesbrough.
Striker Wilson, making his first appearance since suffering knee ligament damage in January, rolled home the Cherries’ second goal from the penalty spot before teeing up substitute Benik Afobe for the clincher.
Debutant defender Jack Simpson had earlier volleyed the hosts into the lead at the Vitality Stadium, before they were pegged back by a first senior goal from Boro teenager Marcus Tavernier.
Leicester City 3-1 Leeds United
Michael Appleton made it two wins from as many matches as caretaker manager after Leicester overcame Leeds to reach the quarter-finals of the Carabao Cup.
Leeds, fourth in the Championship, won at Burnley in the previous round and were on their way towards claiming another Premier League scalp when Pablo Hernandez put them ahead.
However, Kelechi Iheanacho quickly equalised with his first goal for the club and the summer signing from Manchester City set up strike partner Islam Slimani in the second half before substitute Riyad Mahrez scored late on to make it 3-1.
It might prove to be Appleton’s last game at the helm with Leicester’s Thai owners thought to be keen to have a new boss in place for the Premier League visit of Everton on Sunday.
