Key Moments
- Calvert-Lewin sees a first-half header come back off the upright.
- Aaronson puts the hosts ahead with a low finish in the second period.
- Matheus Cunha equalises only three minutes later.
- The Yorkshire side continue their best top-flight undefeated streak since 2001.
Manchester United's poor run of form persisted at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-half effort against the post for the in-form hosts before the American midfielder finished superbly with a driven, 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 Old Trafford earlier in the week.
However, against opponents who had two days less to recover, the forward restored parity three minutes after the opener when he latched onto a pass from introduced Joshua Zirkzee and guided a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his big-money summer move and came at a time when the manager is without several key attacking players due to a combination of injury and international duty.
Not that you would expect the hosts to sympathise with 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 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 contest, also fired against a post late on.
The draw prolongs Leeds' unbeaten run to seven games, their longest such streak since 2001, 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, squandered.
Man Utd Analysis: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be forgiven for hoping the involved countries make a swift 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 absent players are the answer to all of United's problems. After all, they were part of the side that suffered disappointing results earlier in the season.
But without them, the boss has few alternatives in attack.
He evidently does not trust youngster Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost instantly after his introduction as a replacement.
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 showing, the expensive frontman looks similar to 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.
