Key Moments
- Calvert-Lewin sees a early header ricochet off the post.
- Aaronson puts the home side ahead with a well-placed strike in the second half.
- Cunha equalises just three minutes afterwards.
- The Yorkshire side continue their best Premier League unbeaten run since the turn of the century.
Manchester United's disappointing recent struggles persisted at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for the team not suffering even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-period effort against the post for the in-form hosts before the American midfielder applied a cool finish with a low, 62nd-minute effort.
With the goal, the United boss was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against opponents who had two days less to prepare, the forward levelled three minutes later when he ran on to a through ball from substitute Joshua Zirkzee and slid a shot underneath advancing 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 Amorim is without four key attacking players due to a combination of fitness issues and international duty.
Not that the hosts to care about that given their own lack of preparation time.
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 close range.
Cunha, who had a goal ruled out for offside much earlier in the contest, also fired against a post in the dying moments.
The draw prolongs Leeds' unbeaten run to seven matches, their longest such streak since 2001, and takes them eight points 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.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability 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 limited alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost instantly after his arrival as a substitute.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks similar to previous underwhelming signings, lacking in belief and conviction in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the new signing.
Leeds Analysis: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected fervor, but the hostile edge was not as evident as in previous encounters.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an rare moment of threat in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for the opener.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the season, many speculated about the manager's position.
Instead, he is now masterminding clear improvement.
The job is not completed yet but step by step, Leeds are getting closer to achieving their survival.
What Happens Next?
Leeds 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 Premier League trip to Burnley before also entering their FA Cup journey with a home tie.
