Key Moments
- Calvert-Lewin watches a early header ricochet off the post.
- Brenden Aaronson fires the home side ahead with a low strike in the second half.
- Matheus Cunha levels just three minutes later.
- Leeds extend their longest top-flight unbeaten run since 2001.
The Red Devils' poor recent struggles persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more damage against their old rivals.
The Everton loanee directed a first-period effort against the woodwork for the in-form hosts before the American midfielder finished superbly with a driven, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had two days less to prepare, the forward restored parity three minutes later when he ran on to a pass from introduced the Dutchman and slid a finish underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth goal since his big-money summer move and came at a time when the manager is without four key attacking players due to a combination of fitness issues and national team commitments.
Not that Leeds to sympathise with that given their own lack of preparation time.
Noah Okafor forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling 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 fired against a post late on.
The point extends Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a short time, wasted.
Manchester United Breakdown: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other attackers is having on the team'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 suffered disappointing results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He clearly does not trust teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost instantly after his arrival as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds Analysis: Another Step Towards Survival
After memorable victories in their last few home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of expected atmosphere, but the hostile edge was not as evident as in previous encounters.
The home fans were more concerned about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The striker's header that clipped the post was an isolated moment of quality in a congested first half.
It still felt as though the hosts were struggling when a defensive error opened the door for Aaronson.
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 Daniel Farke and the club to deal with.
When they endured a difficult run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now masterminding significant progress.
The job is not done yet but gradually, Leeds are getting closer to achieving their survival.
What Happens Next?
Leeds have a Premier League trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Burnley before also beginning their cup journey with a Old Trafford tie.
