Chelsea survived an FA Cup scare as Conor Gallagher came off the bench to score a last-minute winner and seal a 3-2 victory over Leeds at Stamford Bridge.

The substitute lashed the ball past the visitors’ goalkeeper Illan Meslier to grab what had looked an unlikely victory for much of the game, never more so than when the Blues fell behind inside eight minutes to the first of two goals from Mateo Joseph.

Mauricio Pochettino’s side rallied and looked to have put their woeful start behind them when first Nicolas Jackson and then Mykhailo Mudryk netted to send them in 2-1 up at the break.

Leeds would not lie down easy though, and Joseph headed them level after evading Trevoh Chalobah at the far post on the hour mark.

The home support bubbled with disquiet, sensing another cup mishap after Sunday’s Carabao Cup final loss to Liverpool.

Then came Gallagher’s late intervention to keep hopes of a Wembley return in May alive.

The opening 10 minutes were dominated by Leeds. They might have taken the lead when Daniel James found space on the edge of the box and acrobatically lobbed an effort wide.

It was a let-off for Chelsea, but they did not heed their good fortune. From the goal-kick, Axel Disasi played a short pass inside the penalty area that left Moises Caicedo vulnerable. Leeds snapped at his heels, dispossessing him, and the ball broke to Joseph, who cracked it past Robert Sanchez as Chelsea’s defence pointed fingers.

The first mutterings of discontent among the home support started, but they were doused before they had time to take hold. Caicedo made partial amends for his earlier error, sliding a precise ball through that split Leeds’ defence. Into the space strode Jackson, and he placed it into Meslier’s bottom corner to ease Chelsea nerves.

Thereafter they settled, and deservedly took the lead after 37 minutes. Noni Madueke carried the ball up through midfield and poked it to Malo Gusto wide on the right. He fed Raheem Sterling, who crossed for Mudryk to cap the move with a delightful finish, glancing it with a deft right foot wide of the goalkeeper and in.

James skied one over the bar from six yards as Leeds threatened an instant reply. Jaidon Anthony went closer when he curled wide from outside the box, a reminder that a stiff challenge might await Chelsea in the second half.

Daniel Farke’s team had won nine in a row in the league. Here they went up against Premier League opponents with the courage and skill to suggest they would fare well should they return to the top flight, but their hosts were giving ample encouragement.

The equaliser was straight forward and entirely avoidable from Chelsea’s point of view. Anthony was given space on the right to assess options and size up a cross. Stealing away at the far post was Jospeh, and his marker Chalobah paid him little heed as he stepped outside the defender and nodded past an exposed Sanchez.

The murmurs of disapproval began again from the stands, though they were largely drowned out by the away fans’ vocal support. They deserved better than the heartbreak that came as the clock ticked over to 90 minutes.

Enzo Fernandez was the architect of the winner, darting infield and through the heart of the defence and finally finding the pass that Chelsea had craved throughout the half. Gallagher, with fresh legs from the bench, let the ball run across him and with a swing of his right boot lashed Chelsea into the quarter-finals.

Preston turned the form book on its head as they edged out high-flying 10-man Leeds 2-1 at Deepdale.

Liam Millar was the North End hero, firing home brilliantly into the top corner to win a dramatic game in the 89th minute.

Leeds blew their chance to close the gap on the Championship’s top two after keeper Illan Meslier inexplicably earned himself a straight red card early in the second half.

With a full house watching on, the Roses battle atmosphere was white hot as the two teams got under way for the early kick-off.

The first opportunity went Leeds’ way. Djed Spence made a purposeful break down the left and crossed in for Joel Piroe, but his strike was blocked.

There was an even better block at the other end soon after when Glen Kamara expertly got in the way of Ben Whiteman’s shot.

Given Preston boss Ryan Lowe’s much-publicised backing from the club hierarchy during the week, there was certainly no hint of pressure early on as the stuttering hosts – and their fans – were giving it everything.

Canadian winger Millar whipped in a terrific cross, but skipper Alan Browne missed it by inches.

Millar then fluffed a great chance when, after being found in acres of space by Brad Potts, he blazed woefully over the top from 18 yards.

Millar went much closer in the 34th minute, with a brilliant curling effort from an angle forcing Meslier to produce a super save to keep the scores level.

Leeds’ cause was seriously hindered just eight minutes after the restart when a total loss of discipline cost Meslier dearly.

After initially clashing with Whiteman following a comfortably-taken cross from the right, the Leeds keeper then pushed striker Milutin Osmajic in the face after he had intervened and left referee Josh Smith reaching straight to his top pocket for the red card.

Just two minutes later, and with sub keeper Karl Darlow now having replaced Piroe, Leeds fell behind.
Browne found space in the box as he headed home Millar’s pinpoint cross.

Preston, clearly buoyed and now with a goal and a man advantage, fluffed a decent chance to make it two at the three-quarter point of the game when Browne this time smashed wastefully over the top from the edge of the box.

Georginio Rutter went close for the 10 men, before parity was restored, somewhat against the run of play, in the 83rd minute.

Dan James jinked into the box before being tripped by McCann, leaving skipper Pascal Struijk to slot home from the spot to make it 1-1.

However, that was not enough to earn Leeds a point as Millar darted into the visitors’ box before curling home sweetly to seal the deal just before the game headed into added time.

Leeds manager Daniel Farke felt his side’s 1-0 victory at Championship leaders Leicester was a reward for a performance of “bravery and courage”.

Georginio Rutter’s 57th-minute goal was enough to make sure Leeds closed in on Ipswich in second place, and condemn Leicester to their second home defeat of the season.

Farke praised an impressive display from Leeds, who took the game to Leicester early on and produced what was a statement win at the King Power Stadium.

“We were brave and went for it with courage as a side who have been unbeaten for so long,” said the Leeds manager.

“It was a complex performance on the field, but we stayed disciplined and kept them to areas where they couldn’t hurt us. I believed in my players and that they could dominate the game.

“You could see the goal coming in the second half, it was a deserved win, we had the better chances.

“The only thing Georginio needed to improve was his goal tally. This was a decisive goal and a sign of quality.”

Farke highlighted the fact that Leeds’ players celebrated with goalkeeper Illan Meslier after the game.

The Frenchman produced a superb save to keep out a stoppage-time header from Leicester’s Kiernan Dewsbury-Hall.

“If you want to achieve something special, you need unity,” added the German coach. “That is why the players celebrated Illan’s save. He is a diamond, if he continues to produce performances like this we are definitely on the right path, I think he is the best keeper in the league.

“I also felt that Glen Kamara had his best game in a white shirt.

“For us at the moment, the table is not important. Whatever the outcome here, everything would be possible for both sides. But it was a massive three points for us, a great boost. It was a good night for us.

“But Leicester are such a good side, I’m sure at the end of the season they’ll be in a top position.”

Farke admitted he was “disappointed” to be shown a yellow card for protesting against referee Dean Whitestone’s decision to wave away appeals after Crysencio Summerville went down under pressure from Ricardo Pereira.

“It was only my second yellow card in over 200 games in English football,” he said. “I was a bit disappointed, for me it was definitely a foul. Was it a penalty or a free-kick and a red card.  He didn’t whistle anything, it was a decisive moment.”

Leicester had been aiming for a  10th successive win, but they remain 11 points clear of Leeds in third spot.

Abdul Fatawu hit the crossbar in the first half, but Leicester managed only one effort on target during the game.

“I’m happy with the performance, we expected this match in terms of intensity,” said Leicester manager Enzo Maresca.

“They are a very good team, dangerous and good technically. We cannot win all the games. Overall I am happy, defeat is part of the process. It’s a case of what we can do better, and for sure, we can do some things better.

“I felt we deserved something more from the game.”

Maresca said he felt that, while Leeds took the three points, it had been Sunderland in the previous home game that had offered more in the way of tempo.

“Sunderland were more aggressive and more consistent,” said the Italian. “They started in minute one and finished in minute 95.

“Leeds started with intensity in the first half, and they dropped in the last minutes. We were in control for the last half hour. For me, the team that showed more intensity was Sunderland.”
