At a Glance
- Calvert-Lewin watches a first-half header come back off the upright.
- Aaronson puts the home side ahead with a low strike in the second period.
- Matheus Cunha responds only three minutes afterwards.
- The Yorkshire side extend their best Premier League unbeaten run since the turn of the century.
The Red Devils' poor run of form continued at Leeds' fortress, but manager Ruben Amorim had Matheus Cunha to thank for the team not suffering even more damage against Leeds.
Dominic Calvert-Lewin directed a first-period attempt against the post for the confident home team before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
With the goal, the United boss was under intense scrutiny after his side had been held by bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had less time to recover, Cunha restored parity three minutes after the opener when he ran on to a pass from introduced the Dutchman and slid a finish underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a combination of fitness issues and international duty.
Not that you would expect the hosts to sympathise with that given their own lack of preparation time.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impact, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the contest, also fired against a post late on.
The draw extends the home side's unbeaten run to seven games, their longest such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the involved countries make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's squad.
It's not that the absent players are the answer to all of United's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, the boss has few alternatives in attack.
He clearly does not have full faith in youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the assist for the equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Safety
After thrilling victories in their last few home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of expected fervor, but the intimidating edge was not as evident as in other encounters.
The home fans were more preoccupied about their side's inability to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for Aaronson.
For a short moment, Leeds' ecstatic fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for Daniel Farke and the club to deal with.
When they endured a difficult run of form earlier in the season, many thought about the manager's position.
In contrast, he is now masterminding significant progress.
The task is not done yet but gradually, Leeds are getting closer to securing their survival.
What Happens Next?
The Yorkshire club have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Turf Moor before also beginning their cup journey with a Old Trafford tie.
