Key Moments
- Dominic Calvert-Lewin sees a early header come back off the post.
- Aaronson fires the hosts ahead with a well-placed effort in the second period.
- Cunha equalises just three minutes later.
- Leeds continue their best top-flight unbeaten run since the turn of the century.
Manchester United's poor run of form continued at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more damage against their old rivals.
The Everton loanee directed a first-period attempt against the woodwork for the in-form hosts before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, the United boss was in the firing line after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had two days less to recover, the forward restored parity three minutes after the opener when he ran on to a pass from introduced Joshua Zirkzee and guided a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his big-money summer move and came at a time when the manager is without four key attacking players due to a mix of fitness issues and national team commitments.
Not that the hosts to care about that given their own tight schedule.
Noah Okafor forced a diving save out of visiting 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 Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post late on.
The draw extends 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 Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated 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 disappointing results earlier in the campaign.
But without them, Amorim has few attacking options.
He clearly does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost instantly after his introduction as a substitute.
That leaves the Brazilian, who has now scored three goals in recent outings, and others operating out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and conviction in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Safety
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 fixtures.
Leeds' fans were more preoccupied about their side's inability 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.
Ever so briefly, Leeds' ecstatic 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 Leeds to deal with.
When they endured a difficult run of form earlier in the campaign, many speculated about the manager's position.
In contrast, he is now masterminding clear improvement.
The task is not completed yet but step by step, Leeds are getting closer to achieving their top-flight status.
Looking Ahead
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also entering their FA Cup journey with a home tie.
