Key Moments
- Calvert-Lewin sees a first-half header come back off the post.
- Aaronson fires the home side ahead with a well-placed effort in the second half.
- Cunha levels just three minutes later.
- The Yorkshire side extend their longest Premier League unbeaten run since 2001.
The Red Devils' poor recent struggles persisted at Leeds' fortress, but head coach Ruben Amorim had Matheus Cunha to thank for the team avoiding even more disappointment against their old rivals.
The Everton loanee directed a first-half effort against the post for the confident hosts before the American midfielder finished superbly with a driven, 62nd-minute shot.
At that stage, the United boss was under intense scrutiny after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against a team who had two days less to recover, the forward levelled three minutes after the opener when he ran on to a through ball from introduced the Dutchman and slid a shot underneath advancing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth 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 national team commitments.
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 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 six yards out.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post late on.
The point extends Leeds' unbeaten run to seven games, 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 fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, the United coach could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other attackers is having on Amorim's options.
It's not that the absent players are the solution 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, the boss has few alternatives in attack.
He evidently does not trust youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to previous struggling signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds Analysis: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of typical fervor, but the intimidating edge was not as evident as in other encounters.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an rare moment of threat in a tight first half.
It still felt as though Leeds 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.
However, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they suffered a difficult run of form earlier in the season, many speculated about the manager's future.
In contrast, he is now masterminding significant improvement.
The task is not done yet but gradually, the team are getting closer to securing their top-flight status.
Looking Ahead
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Burnley before also beginning their FA Cup journey with a Old Trafford tie.
