Key Moments
- Calvert-Lewin watches a first-half header ricochet off the post.
- Aaronson puts the hosts ahead with a low strike in the second period.
- Cunha equalises only three minutes afterwards.
- The Yorkshire side continue their longest top-flight undefeated streak since 2001.
The Red Devils' disappointing run of form persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more disappointment against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the woodwork for the in-form hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
At that stage, the United boss was in the firing line after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to recover, the forward levelled three minutes later when he ran on to a through ball from substitute the Dutchman and slid a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American'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 international duty.
Not that you would expect the hosts to sympathise with that given their own lack of preparation time.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, wasted.
Man Utd Analysis: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the participating nations make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other attackers is having on Amorim's squad.
It's not that the missing pair are the solution to all of United's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, Amorim has limited attacking options.
He clearly does not trust youngster Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for the equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous struggling 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 new signing.
Leeds United Breakdown: Another Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of expected fervor, but the hostile edge was not as pronounced as in previous encounters.
The home fans were more concerned about their side's struggle to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that clipped the post was an rare moment of threat in a congested first half.
It still felt as though the hosts were struggling when a defensive error opened the door for the opener.
Ever so briefly, The home delirious fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for the manager 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.
In contrast, he is now overseeing significant progress.
The task is not completed yet but gradually, Leeds are getting nearer to achieving their top-flight status.
Looking Ahead
The Yorkshire club have a Premier League trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also beginning their FA Cup journey with a home tie.
