Key Moments
- Calvert-Lewin sees a first-half header ricochet off the post.
- Aaronson puts the home side ahead with a low strike in the second half.
- Cunha levels only three minutes later.
- Leeds continue their longest Premier League undefeated streak since 2001.
The Red Devils' disappointing run of form persisted at Elland Road, but manager the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the post for the confident home team before the American midfielder applied a cool finish with a low, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had two days less to prepare, the forward restored parity three minutes later when he ran on to a through ball from introduced Joshua Zirkzee and slid a shot underneath rushing 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 several key attacking players due to a combination of injury and national team commitments.
Not that you would expect Leeds to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of Manchester United 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 impression, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The draw prolongs the home side's unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood 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 attackers is having on the team's squad.
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 disappointing results earlier in the campaign.
But without them, the boss has limited attacking options.
He clearly does not have full faith in youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others operating out of their natural positions, alongside Sesko.
On this evidence, the expensive frontman looks no better than previous struggling signings, lacking in belief and assurance 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 United Breakdown: Another Step Towards Survival
After memorable victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of expected atmosphere, but the hostile edge was not as pronounced 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 striker's header that struck the post was an rare moment of quality in a tight first half.
It still felt as though Leeds were finding it tough 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 their old foes.
Nevertheless, there is a wider context for Daniel Farke and the club to deal with.
When they suffered a difficult run of form earlier in the campaign, many thought about the manager's future.
In contrast, he is now overseeing clear improvement.
The task is not done yet but step by step, the team are getting closer to securing their survival.
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. Manchester United face a Premier League trip to Turf Moor before also entering their cup journey with a home tie.
