At a Glance
- Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson fires the hosts ahead with a well-placed finish in the second half.
- Matheus Cunha responds just three minutes afterwards.
- Leeds continue their longest top-flight unbeaten run since 2001.
The Red Devils' disappointing recent struggles persisted at Elland Road, but manager Ruben Amorim had Matheus Cunha to thank for his side not suffering even more damage against their old rivals.
The Everton loanee headed a first-period effort against the woodwork for the in-form home team before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
With the goal, 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.
Nevertheless, against opponents who had two days less to recover, Cunha restored parity three minutes later when he latched onto a through ball from substitute the Dutchman and slid a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian'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 national team commitments.
Not that you would expect the hosts to care about that given their own tight schedule.
Noah Okafor forced a diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned his teammate'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 games, their longest such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim'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, Amorim has limited alternatives in attack.
He clearly does not have full faith in youngster 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 five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous struggling signings, lacking in confidence and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of typical fervor, but the intimidating edge was not as pronounced as in previous fixtures.
The home fans were more preoccupied about their side's inability to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an rare moment of threat in a tight first half.
It still felt as though Leeds were struggling when a defensive error opened the door for Aaronson.
For a short moment, 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 season, many thought about the manager's position.
Instead, he is now masterminding clear improvement.
The job is not completed yet but gradually, Leeds are getting nearer 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 FA Cup journey with a Old Trafford tie.
