Key Moments
- Calvert-Lewin sees a early header ricochet off the upright.
- Aaronson fires the home side ahead with a low effort in the second period.
- Matheus Cunha responds just three minutes later.
- Leeds continue their best top-flight undefeated streak since 2001.
Manchester United's poor recent struggles continued at Elland Road, but manager the Portuguese tactician had Matheus Cunha to thank for his side avoiding even more damage against their old rivals.
The Everton loanee headed a first-half attempt against the woodwork for the confident hosts before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against opponents who had less time to recover, Cunha restored parity three minutes later when he ran on to a through ball from introduced Joshua Zirkzee and slid a finish underneath advancing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a mix of injury and international duty.
Not that you would expect 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 Benjamin Sesko, who is finding it hard to make an impression, turned his teammate's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post in the dying moments.
The draw prolongs Leeds' unbeaten run to seven games, their longest such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity 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 knockout phase, the United coach could be forgiven for hoping the participating nations 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 options.
It's not that the absent players are the answer to all of the club's problems. After all, they were part of the side that suffered poor results earlier in the season.
But without them, the boss has few attacking options.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost immediately after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were instances of expected fervor, but the intimidating edge was not as pronounced as in previous encounters.
The home 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 clipped the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were struggling when a mistake opened the door for Aaronson.
For a short moment, The home delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a much bigger picture for the manager and Leeds to deal with.
When they suffered a poor run of form earlier in the campaign, many speculated about the manager's position.
Instead, he is now masterminding clear improvement.
The job is not completed yet but gradually, Leeds are getting nearer to achieving their top-flight status.
Looking Ahead
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 Premier League trip to Turf Moor before also entering their FA Cup journey with a home tie.
