At a Glance
- Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson fires the hosts ahead with a well-placed effort in the second half.
- Matheus Cunha levels just three minutes afterwards.
- Leeds continue their longest Premier League unbeaten run since the turn of the century.
The Red Devils' disappointing run of form continued at Elland Road, but manager Ruben Amorim had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-period effort against the woodwork for the confident hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to prepare, the forward restored parity three minutes after the opener when he latched onto a pass from introduced the Dutchman and guided a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American'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 you would expect Leeds to sympathise with that given their own tight schedule.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also fired against a post late on.
The draw extends Leeds' unbeaten run to seven matches, their best such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, wasted.
Manchester United Breakdown: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other forwards is having on Amorim's squad.
It's not that the absent players are the solution to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the campaign.
But without them, Amorim has limited attacking options.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in recent outings, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in confidence and conviction in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds Analysis: A Further Step Towards Survival
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 moments of expected fervor, but the hostile edge was not as pronounced as in previous fixtures.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an rare moment of threat in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for the opener.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against their old foes.
However, there is a much bigger picture for the manager and Leeds to deal with.
When they endured a poor run of form earlier in the campaign, many speculated about the manager's position.
In contrast, he is now masterminding clear progress.
The job is not completed yet but gradually, Leeds are getting closer to securing their survival.
What Happens Next?
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also beginning their FA Cup journey with a Old Trafford tie.
