At a Glance
- Dominic Calvert-Lewin sees a early header come back off the post.
- Aaronson puts the hosts ahead with a low finish in the second period.
- Cunha levels just three minutes later.
- The Yorkshire side continue their longest top-flight undefeated streak since 2001.
Manchester United's disappointing recent struggles persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against Leeds.
The Everton loanee headed a first-period effort against the woodwork for the in-form home team before the American midfielder 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 failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to recover, the forward levelled three minutes after the opener when he ran on to a pass from substitute Joshua Zirkzee and guided 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 Amorim is without several key attacking players due to a mix of fitness issues and international duty.
Not that the hosts to care about that given their own tight schedule.
The Swiss attacker forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impression, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The draw prolongs the home side's unbeaten run to seven games, 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 chance to move into the Champions League places, albeit only for a short time, squandered.
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.
Current injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on the team's squad.
It's not that the missing pair are the solution to all of the club's problems. After all, they were part of the side that experienced poor results earlier in the season.
But without them, Amorim has limited attacking options.
He clearly does not trust teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: Another Step Towards Survival
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were instances of typical fervor, but the intimidating edge was not as evident as in previous fixtures.
The home fans were more preoccupied about their side's struggle to get sustained possession in dangerous areas for any length of time.
The striker's header that struck the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were finding it tough 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.
However, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's position.
In contrast, he is now overseeing clear progress.
The job is not completed yet but gradually, Leeds are getting nearer to achieving their survival.
Looking Ahead
The Yorkshire club 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 beginning their cup journey with a Old Trafford tie.
