Key Moments
- Dominic Calvert-Lewin sees a first-half header come back off the post.
- Aaronson puts the home side ahead with a well-placed strike in the second half.
- Matheus Cunha responds just three minutes later.
- Leeds extend their best Premier League undefeated streak since the turn of the century.
The Red Devils' disappointing recent struggles continued at Elland Road, but manager Ruben Amorim had Matheus Cunha to thank for the team avoiding even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-half effort against the post for the confident hosts before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
However, against a team who had two days less to prepare, the forward restored parity three minutes later when he ran on to a pass from introduced the Dutchman and slid a shot underneath rushing home goalkeeper Lucas Perri.
It was only the South American's fourth goal since his big-money summer move and came at a time when the manager is without several key attacking players due to a mix of injury and national team commitments.
Not that you would expect Leeds to sympathise with that given their own tight schedule.
Noah Okafor forced a full length save out of visiting 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 impression, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also fired against a post late on.
The point prolongs Leeds' unbeaten run to seven games, their longest 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 opportunity to move into the Champions League places, albeit only for a short time, wasted.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other forwards 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 few attacking options.
He clearly does not trust youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost instantly after his arrival as a substitute.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others operating out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks no better than 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 Analysis: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of expected atmosphere, but the intimidating edge was not as pronounced as in previous encounters.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in advanced areas for any length of time.
