At a Glance
- Calvert-Lewin sees a early header ricochet off the upright.
- Aaronson puts the hosts ahead with a low strike in the second half.
- Cunha levels just three minutes later.
- The Yorkshire side continue their best Premier League unbeaten run since 2001.
The Red Devils' disappointing recent struggles continued at Elland Road, but manager Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-period attempt against the woodwork for the in-form hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
However, against a team who had two days less to recover, Cunha restored parity three minutes after the opener when he latched onto a pass from substitute Joshua Zirkzee and slid a shot 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 four key attacking players due to a mix of injury and national team commitments.
Not that the hosts to sympathise with that given their own tight schedule.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United 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 match, also blasted against a post late on.
The draw extends Leeds' unbeaten run to seven games, their longest such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, wasted.
Manchester United Breakdown: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated 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 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 evidently does not trust 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 playing out of their natural positions, alongside Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming 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 young striker.
Leeds Analysis: Another Step Towards Survival
After memorable victories in their last few 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 intimidating edge was not as evident as in other fixtures.
The home fans were more concerned about their side's struggle to get worthwhile possession in advanced areas for any length of time.
The striker's header that struck the post was an rare moment of threat in a congested first half.
It still felt as though Leeds were struggling when a mistake opened the door for the opener.
For a short moment, Leeds' ecstatic fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a wider context for Daniel Farke and Leeds to deal with.
When they endured a difficult run of form earlier in the season, many speculated about the manager's future.
Instead, he is now overseeing significant progress.
The job is not completed yet but step by step, the team are getting nearer to securing their survival.
Looking Ahead
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Burnley before also entering their cup journey with a home tie.
