At a Glance
- Dominic Calvert-Lewin sees a first-half header come back off the upright.

- Cunha levels just three minutes later.
- The Yorkshire side extend their longest Premier League undefeated streak since 2001.
The Red Devils' disappointing run of form continued at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more damage against their old rivals.
The Everton loanee directed a first-half attempt against the post for the confident home team 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 Wolves at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to prepare, the forward levelled three minutes after the opener when he latched onto a through ball from introduced Joshua Zirkzee and guided a shot underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his high-profile summer move and came at a time when Amorim is without several key attacking players due to a mix of injury and national team commitments.
Not that Leeds to care about that given their own lack of preparation time.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a audacious 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 six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post late on.
The point extends the home side's unbeaten run to seven games, their longest such streak since 2001, and takes them a significant margin 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, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, 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 absence of other attackers is having on Amorim's squad.
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 experienced disappointing results earlier in the campaign.
But without them, Amorim has limited alternatives in attack.
He clearly does not have full faith in youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost immediately 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 natural 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 Zirkzee's cross means it is now a long run without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were moments of typical atmosphere, but the hostile edge was not as evident as in previous encounters.
Leeds' fans were more concerned about their side's inability to get sustained possession in dangerous areas for any length of time.
The striker's header that struck the post was an rare moment of quality in a congested first half.
It still felt as though Leeds were struggling when a mistake opened the door for Aaronson.
For a short moment, The home ecstatic fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for the manager and the club to deal with.
When they suffered a difficult run of form earlier in the season, many speculated about the manager's future.
Instead, he is now masterminding clear progress.
The job is not completed yet but step by step, the team are getting nearer to securing their top-flight status.
What Happens Next?
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also beginning their cup journey with a home tie.
