Key Moments
- Calvert-Lewin sees a early header come back off the upright.
- Aaronson fires the home side ahead with a low strike in the second period.
- Cunha responds just three minutes afterwards.
- The Yorkshire side extend their best top-flight unbeaten run since 2001.
Manchester United's poor run of form continued at Elland Road, but head coach the Portuguese tactician had Matheus Cunha to thank for his side not suffering even more disappointment against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the post for the confident hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolves at home earlier in the week.
However, against a team who had two days less to prepare, Cunha levelled three minutes after the opener 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 South American'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 sympathise with that given their own lack of preparation time.
The Swiss attacker 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.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also fired against a post in the dying moments.
The draw extends Leeds' unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, wasted.
Man Utd Analysis: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other attackers is having on Amorim's squad.
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 disappointing results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the assist for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their preferred positions, alongside Sesko.
On this showing, the expensive frontman looks similar to previous struggling signings, lacking in belief and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Safety
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 moments of expected fervor, but the intimidating edge was not as evident as in other fixtures.
The home fans were more preoccupied about their side's inability to get worthwhile possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a rare win against Manchester United.
However, there is a wider context 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 overseeing clear progress.
The job is not completed yet but gradually, Leeds are getting closer to achieving their top-flight status.
Looking Ahead
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also beginning their FA Cup journey with a Old Trafford tie.
