Amad Diallo settled a thrilling FA Cup quarter-final with a last-gasp strike in extra-time as Manchester United beat Liverpool 4-3 to end the Reds' hopes of a quadruple in Jurgen Klopp's final season in charge.
Erik ten Hag's side took the tie into extra-time after substitute Antony struck in the 87th minute, and after falling behind again to Harvey Elliott's deflected strike, Marcus Rashford and then Amad scored to set up a semi-final against Championship side Coventry City at Wembley Stadium on the weekend of 20-21 April.
In the day's other quarter-final, Chelsea edged past 10-man Leicester City 4-2 thanks to stoppage-time goals from substitutes Carney Chukwuemeka and Noni Madueke. The Blues will face holders Manchester City in the semi-finals, after Pep Guardiola's men beat Newcastle United 2-0 on Saturday.

What do the results mean for Premier League fixtures?

Amad settles epic cup tie
Ten Hag was able to hand recalls to the fit-again Rasmus Hojlund and Aaron Wan-Bissaka, with Casemiro and Jonny Evans not named in the matchday squad.
Mohamed Salah was included in Liverpool's starting XI, while Virgil van Dijk, Alexis Mac Allister and Luis Diaz came back into the side.
After a breathless start to the contest, Man Utd went in front in the 10th minute through Scott McTominay. Liverpool goalkeeper Caoimhin Kelleher could only parry Alejandro Garnacho's shot into the path of the Scot, who tucked away the rebound.
Liverpool turned the cup tie on its head with two goals at the end of the first half.
First Darwin Nunez laid the ball off for Mac Allister, whose shot took a deflection off the boot of Kobbie Mainoo before going in.
Then in the second minute of added time, Nunez's shot was spectacularly saved by Andre Onana, only for the ball to fall to Salah, who took a touch before lashing in.
Ten Hag introduced Antony, Amad and Christian Eriksen from the bench in search of a late equaliser, and with three minutes remaining, Antony spun inside the penalty area before shooting low past Kelleher to level.
Both sides had late chances to win the tie in normal time, with Liverpool substitute Elliott striking against the woodwork before deep into stoppage time, Rashford collected Eriksen's sumptuous chipped pass, but could only guide his shot inches wide of a post.
Liverpool retook the lead in the 105th minute when Elliott's shot from 20 yards out took a deflection off Eriksen and went through the legs of fellow substitute Harry Maguire before nestling into the bottom-left corner.
But back came United and they levelled in the 112th minute through Rashford, who stroked into the bottom-right corner having been played in by McTominay.
After McTominay could only poke a shot agonisingly wide of a post, Elliott lost possession to Amad deep in the Man Utd half following a Liverpool corner.
Garnacho raced forward before passing to Amad, who drove into the penalty area and moved the ball onto his left foot before scuffing a low shot into the bottom-right corner.
Amad, who had already been shown a yellow card six minutes earlier, was booked again for removing his shirt in his celebrations and sent off. But it mattered not as United sealed their semi-final spot.

Late goals send Chelsea through
Mauricio Pochettino made two changes from the team that beat Newcastle 3-2 in the Premier League, with Robert Sanchez replacing Djordje Petrovic in goal while Mykhailo Mudryk came in for the suspended Enzo Fernandez. Ben Chilwell was back among the substitutes for the Blues.
Chelsea took the lead on 14 minutes through Marc Cucurella, who tapped in from close range from Nicolas Jackson's ball across the area.
The Blues had a glorious opportunity to double their advantage when they were awarded a penalty for a foul on Raheem Sterling by Abdul Fatawu, but Sterling's weak spot-kick was comfortably saved by the legs of Jakub Stolarczyk.
Pochettino's side did make it 2-0 in first-half added time when Sterling raced down the left before squaring for Cole Palmer to slot in from six yards.
Chelsea let Leicester back into the match in the 52nd minute when Axel Disasi, who was being pressurised by Patson Daka, overhit his backpass from 35 yards out, and with Sanchez off his line, the ball bounced once before going in.
Leicester then levelled 11 minutes later, Stephy Mavididi driving into the penalty area before bending a shot into the far corner of the net.
But Leicester's hopes of a cup upset were dealt a serious blow when Callum Doyle was sent off after bringing down Jackson when the Chelsea forward was through on goal.
The Blues were initially awarded a penalty and Doyle shown a yellow card, but it was upgraded to a red following a VAR review, while the foul was adjudged to have taken place just outside the penalty area.
The home side's pressure eventually told in the third minute of stoppage time when Palmer's delightful flick was collected by Chukwuemeka, before the midfielder finished through the legs of Stolarczyk.
Palmer has now both scored and assisted in six different matches for Chelsea in all competitions this season, the most of any Premier League player in 2023/24.
Madueke added gloss to the scoreline five minutes later, beating three defenders before curling a terrific shot into the top-left corner.
