At a Glance
- Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson fires the home side ahead with a low effort in the second half.
- Cunha responds only three minutes later.
- Leeds continue their best top-flight unbeaten run since 2001.
The Red Devils' disappointing recent struggles persisted at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more disappointment against Leeds.
The Everton loanee headed a first-period attempt against the post for the in-form home team before the American midfielder applied a cool finish with a low, 62nd-minute shot.
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, the forward restored parity three minutes later when he ran on to a pass from introduced 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 high-profile summer move and came at a time when the manager is without several key attacking players due to a combination of fitness issues and international duty.
Not that you would expect Leeds 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 spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
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 matches, their longest such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a matter of hours, wasted.
Man Utd Analysis: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the participating nations make a swift exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other forwards is having on the team's squad.
It's not that the missing pair are the answer to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks similar to previous underwhelming signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were instances of expected fervor, but the intimidating edge was not as evident as in other fixtures.
The home fans were more preoccupied about their side's inability to get sustained possession in dangerous areas for any length of time.
The Calvert-Lewin header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds were struggling when a defensive error opened the door for Aaronson.
Ever so briefly, The home delirious 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 suffered a difficult run of form earlier in the season, many thought about the manager's future.
In contrast, he is now masterminding significant progress.
The job is not completed yet but gradually, the team are getting closer to securing their survival.
What Happens Next?
