Key Moments
- Calvert-Lewin sees a first-half header ricochet off the upright.
- Brenden Aaronson fires the hosts ahead with a well-placed effort in the second half.
- Cunha levels only three minutes later.
- The Yorkshire side extend their best Premier League unbeaten run since the turn of the century.
Manchester United's disappointing run of form continued at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more disappointment against their old rivals.
The Everton loanee directed a first-period attempt against the post for the in-form hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had less time to prepare, the forward levelled three minutes later when he latched onto a through ball from substitute Joshua Zirkzee and slid a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his big-money 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 sympathise with that given their own lack of preparation time.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard 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 match, also blasted against a post late on.
The draw prolongs the home side's unbeaten run to seven games, their best such streak since over two decades ago, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: Amorim'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 Three Lions star Mason Mount only exacerbated the impact the absence of other forwards is having on the team's options.
It's not that the missing pair are the answer to all of United's problems. After all, they were part of the side that suffered poor results earlier in the season.
But without them, Amorim has limited alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward delivered the through ball for Cunha's equaliser almost instantly after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in recent outings, and others operating out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Survival
After thrilling victories in their last few home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of typical fervor, but the hostile edge was not as evident as in previous fixtures.
The home fans were more preoccupied about their side's inability to get worthwhile possession in dangerous areas for any length of time.
The Calvert-Lewin header that clipped the post was an rare moment of quality in a congested first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, The home ecstatic fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they endured a difficult run of form earlier in the season, many thought about the manager's future.
Instead, he is now overseeing significant improvement.
The task is not done yet but step by step, Leeds are getting closer to securing their survival.
What Happens Next?
