Sometimes, football matches can be beyond explanation. They can be freak occurrences on a pitch involving 22 players and a series of unfortunate events.These moments are rare at the highest level. The use of ultra-negative, restrictive tactics can keep a lid on even the most yawning of mismatches.The biggest gulfs might occasionally emerge if there are several tiers between two sides in a cup tie or in pre-season, when fitness, motivation and concentration can throw up oddities.So Leeds United’s 6-3 collapse at Chelsea in the Carabao Cup on Wednesday can be marked down as one of the most bizarre outcomes in their recent history.This has not happened to Leeds under Daniel Farke very often. Since he was appointed in July 2023, Queens Park Rangers, Arsenal and Newcastle United are the only opponents to put four or more goals past his Leeds sides.In the QPR (4-0 in the 2023-24 Championship) and Arsenal (5-0 and 4-0 in the 2025-26 Premier League) examples, Leeds were demonstrably second-best across the pitch and deservedly dismantled. They were easily explained and criticised.The Newcastle game, a 4-3 away league loss in January, had elements of Wednesday’s back-and-forth madness. It was two boxers dropping their guard to take swings at one another to see whose jaw lasted longest. Chelsea just landed more of their punches than Newcastle.It is rare for Leeds to be this open, but this was an especially punishing night in which clinical finishing met haphazard defending and passive goalkeeping. The statistics had Chelsea and Leeds virtually tied at 2.4 and 2.39 expected goals (xG) respectively, and yet the former hit six to the latter’s three.Even when you take into account the expected goals on target (xGOT) values, a more accurate measure of a shot’s quality after being struck, Chelsea edged it 3.28 to 2.99. Leeds ended up with the tally they deserved, but are left wondering how debutant goalkeeper Michael Zetterer and his defence let the hosts rattle off six.What makes it all the more puzzling is how dominant Leeds were in this game. Unlike that loss to Newcastle, which was end-to-end all night, Farke’s side had Stamford Bridge in the palm of their hand beyond the 50th minute, but let it escape their grasp.The blue cavalry had inevitably arrived at half-time in Cole Palmer, Morgan Rogers, Reece James and Pedro Neto, but Brenden Aaronson’s 48th-minute goal to put the visitors 2-0 up, which followed a dominant first half, should have given Leeds the breathing room they needed to see this out. As it was, four concessions in 12 minutes defined the evening.Brenden Aaronson’s goal looked to have put Leeds in control at Chelsea (Adrian Dennis/AFP via Getty Images)In his press conference afterwards, Farke said: “The key message is one small situation in football can change the world and can change all momentum of the game.” The turning point was referee Jarred Gillett’s decision to award Chelsea a penalty in the 53rd minute.Daniel James challenged Pep Chavarria, but any contact between their boots was minimal. Nobody in blue appealed for a spot kick, but Gillett decided to give Palmer the canvas on which to paint the comeback. It set a wild 12 minutes in motion.“After a cheap throw-in situation, we underestimate; we didn’t follow the movement of Palmer,” said Farke. “He’s a quality player and he puts the ball into the corner, 2-2 out of nothing.“This little situation to give the penalty and not to follow the movement after the throw-in changed the whole momentum. The stadium was bouncing; their body language was on it.“We could have done better afterwards in a few situations; there is no doubt about this. Quality players like them also use this, but it also felt a bit like each of their strikes on our goal was a goal.”Leeds were consistently punished for every error or oversight. On that second goal, Tarik Muharemovic should do more to disrupt Rogers under the throw, Sean Longstaff should be more aware of Palmer’s movement and Zetterer, one of the big casualties of the night, has to do better with the finish.Based on that xGOT tally, Palmer and Danny Welbeck’s second goals were rated at 0.1 and 0.37 respectively. They were shots Zetterer would be expected to save, more often than not, and he was unable to.For the third Chelsea goal, via Neto, Harry Wilson’s half-pass-half-tackle was spooned to an unmarked Palmer in the centre. Chelsea’s No 10 should never have been allowed that much space and the counter caught Leeds out of shape, with Melvin Bard understandably having to go to Rogers and leaving Neto unmarked in the process.Chelsea hit those three goals in seven breathless minutes. It was not until the third went in that we saw Farke summon four substitutes. By the time they were ready to come on, Welbeck had scored the fourth, which again featured Muharemovic being beaten by Rogers down the flank, while Jaka Bijol was caught challenging the scorer in slow motion.Could Farke have reacted more quickly to what was unfolding? Yes. Is that with hindsight, however? Leeds had been in control. Farke was right to see how they coped with Chelsea’s half-time changes, but once the goals started flying in, it was relentless.Even if he had asked for his substitutes to get ready at 2-1, which would have felt premature, it would have been 2-2 by the time they entered the field. In hindsight, making a decisive call at 2-2, in the 55th minute, five minutes before 3-2, would have been prudent.Even then, a dubious penalty and lax marking at a throw were the difference and subs may have felt like a knee-jerk reaction. The Leeds players on the pitch should have managed the game better.At 2-2, with the pressure growing, they had to find a way to kill the home momentum. Whether that meant going down with an injury to break up the flow or sitting in with a solid, deep shape for five minutes, the storm needed to be weathered.Understandably, supporters may wonder if this disintegration should pose any lasting cause for concern. In short: no. This was a rare off-night in what has been a remarkable nine months.Chelsea wildly outperformed their statistics, which Leeds actually matched. James Trafford will return to the side. This was a heavily rotated team without the usual level of cohesion. That will not be the case on Monday.Ironically, Leeds will play Newcastle under the lights again in their next game, at Elland Road, when fans will want early reassurance this was a one-off.
