Match Summary
Manchester United's disappointing run of form persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more disappointment against Leeds.
The Everton loanee headed a first-half effort against the post for the in-form hosts before the American midfielder applied a cool finish with a low, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had two days less to recover, the forward levelled three minutes after the opener when he ran on to a through ball from substitute Joshua Zirkzee and guided a shot underneath rushing Leeds 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 the manager is without four key attacking players due to a combination of fitness issues and national team commitments.
Not that you would expect the hosts to care about that given their own lack of preparation time.
Noah Okafor forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post in the dying moments.
The draw prolongs the home side's unbeaten run to seven matches, their best such streak since over two decades ago, and takes them a significant margin clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, wasted.
With the AFCON reaching its knockout phase, Amorim could be forgiven 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 missing pair are the solution to all of United'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 trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the assist for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the expensive frontman looks no better than previous underwhelming signings, lacking in belief and conviction 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.
After thrilling victories in their last few home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were moments of expected fervor, but the hostile edge was not as pronounced as in other encounters.
The home fans were more concerned about their side's struggle 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 quality in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, The home ecstatic fans thought they were about to secure a coveted win against their old foes.
However, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they endured a poor run of form earlier in the season, many thought about the manager's position.
In contrast, he is now masterminding significant improvement.
The job is not done yet but gradually, the team are getting closer to securing their top-flight status.
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Burnley before also beginning their FA Cup journey with a Old Trafford tie.
