Key Moments
- Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson puts the home side ahead with a low effort in the second period.
- Matheus Cunha equalises only three minutes later.
- The Yorkshire side continue their best Premier League undefeated streak since 2001.
Manchester United's disappointing run of form persisted at Elland Road, but manager Ruben Amorim had his Brazilian forward to thank for the team avoiding even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-half effort against the woodwork for the in-form hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
With the goal, the United boss was in the firing line after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had two days less to recover, the forward levelled three minutes later when he ran on to a pass from substitute the Dutchman and guided a shot underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his big-money summer move and came at a time when the manager is without several key attacking players due to a combination of fitness issues and national team commitments.
Not that Leeds to care about that given their own tight schedule.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The draw prolongs the home side's unbeaten run to seven games, their longest such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the participating nations make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other attackers is having on Amorim's options.
It's not that the missing pair are the answer to all of United's problems. After all, they were part of the side that experienced poor results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for the equaliser almost instantly after his introduction as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their natural positions, alongside Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming signings, lacking in confidence and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds Analysis: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of expected atmosphere, but the hostile edge was not as pronounced as in other encounters.
Leeds' fans were more preoccupied about their side's inability to get sustained possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of threat in a tight first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for the opener.
For a short moment, Leeds' ecstatic fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a much bigger picture for the manager and the club to deal with.
When they suffered a difficult run of form earlier in the season, many thought about the manager's position.
Instead, he is now masterminding clear progress.
The task is not done yet but gradually, Leeds are getting nearer to securing their top-flight status.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also beginning their cup journey with a Old Trafford tie.
