At a Glance
- Dominic Calvert-Lewin watches a first-half header come back off the upright.
- Aaronson puts the hosts ahead with a low finish in the second half.
- Matheus Cunha equalises just three minutes afterwards.
- Leeds extend their best top-flight unbeaten run since the turn of the century.
The Red Devils' disappointing run of form persisted at Elland Road, but manager the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-half attempt against the woodwork for the confident home team before the American midfielder finished superbly with a driven, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had been held by struggling Wolves at home earlier in the week.
Nevertheless, against opponents who had two days less to prepare, the forward restored parity three minutes after the opener when he latched onto a pass from introduced the Dutchman and guided a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth 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 fitness issues and international duty.
Not that the hosts to care about that given their own lack of preparation time.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impact, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the contest, also fired against a post in the dying moments.
The draw prolongs Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin 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.
Man Utd Analysis: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on the team'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 experienced disappointing results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the new signing.
Leeds Analysis: A Further Step Towards Survival
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of typical fervor, but the hostile edge was not as evident as in other fixtures.
The home fans were more preoccupied about their side's struggle to get worthwhile possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an rare moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for Aaronson.
For a short moment, Leeds' ecstatic fans thought they were about to secure a coveted win against their old foes.
However, there is a wider context for the manager and the club to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's position.
Instead, he is now masterminding significant progress.
The job is not done yet but gradually, the team are getting closer to securing their top-flight status.
What Happens Next?
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Turf Moor before also beginning their FA Cup journey with a Old Trafford tie.
