Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the post.
- Aaronson fires the hosts ahead with a well-placed strike in the second half.
- Cunha levels just three minutes afterwards.
- The Yorkshire side continue their best top-flight unbeaten run since the turn of the century.
Manchester United's poor recent struggles continued at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more damage against Leeds.
Dominic Calvert-Lewin directed a first-half attempt against the woodwork for the confident home team before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
At that stage, the United boss was under intense scrutiny after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford 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 the Dutchman and guided a finish underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his big-money summer move and came at a time when Amorim is without four key attacking players due to a mix of injury and international duty.
Not that you would expect Leeds to sympathise with that given their own tight schedule.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impression, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the match, also blasted 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 visitors though, it was yet another opportunity to move into fourth spot, albeit only for a short time, wasted.
Man Utd Analysis: Amorim's Side Struggle 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.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence of other attackers is having on the team's options.
It's not that the absent players are the answer to all of the club's problems. After all, they were part of the side that suffered disappointing results earlier in the season.
But without them, Amorim has limited attacking options.
He clearly does not trust youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the assist for the equaliser almost immediately after his arrival as a replacement.
That leaves the Brazilian, 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 no better than previous underwhelming signings, lacking in confidence 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: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were moments of typical fervor, but the intimidating edge was not as evident as in previous encounters.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that struck the post was an isolated moment of quality in a congested first half.
It still felt as though the hosts were struggling when a defensive error opened the door for the opener.
Ever so briefly, The home ecstatic fans thought they were about to secure a rare win against their old foes.
However, there is a wider context for the manager and the club to deal with.
When they endured a poor run of form earlier in the season, many thought about the manager's future.
Instead, he is now masterminding significant improvement.
The task is not done yet but step by step, Leeds are getting closer to securing their top-flight status.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also beginning their cup journey with a Old Trafford tie.
