Key Moments
- Calvert-Lewin sees a first-half header come back off the upright.
- Aaronson fires the hosts ahead with a well-placed effort in the second half.
- Cunha levels only three minutes afterwards.
- Leeds continue their longest Premier League undefeated streak since the turn of the century.
The Red Devils' poor run of form continued at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for the team avoiding even more disappointment against their old rivals.
The Everton loanee directed a first-half attempt against the woodwork for the in-form home team before the American midfielder applied a cool finish with a low, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha levelled three minutes later when he ran on to a through ball from introduced Joshua Zirkzee and slid a shot underneath advancing home 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 international duty.
Not that Leeds to sympathise with that given their own tight schedule.
Noah Okafor forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting 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 blasted against a post in the dying moments.
The draw extends Leeds' unbeaten run to seven matches, their best such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, wasted.
Manchester United Breakdown: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, the United coach 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 exacerbated the impact the unavailability of other attackers is having on Amorim'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 disappointing results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He clearly does not trust teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward provided the assist for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored a small tally in recent outings, and others operating out of their preferred positions, alongside Sesko.
On this evidence, the expensive frontman looks similar to previous struggling signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Survival
After memorable victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were instances of expected atmosphere, but the hostile edge was not as evident as in other fixtures.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in advanced areas for any prolonged period.
The striker's header that clipped the post was an isolated moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for the opener.
For a short moment, The home 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 the club 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 significant improvement.
The job is not completed yet but step by step, Leeds are getting nearer to achieving their survival.
Looking Ahead
The Yorkshire club 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 cup journey with a Old Trafford tie.
