At a Glance
- Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson fires the hosts ahead with a well-placed strike in the second half.
- Matheus Cunha levels only three minutes afterwards.
- The Yorkshire side extend their longest Premier League undefeated streak since the turn of the century.
The Red Devils' poor recent struggles persisted at Elland Road, but head coach the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more damage against Leeds.
The Everton loanee directed a first-period attempt against the woodwork for the confident hosts before Brenden Aaronson finished superbly with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against a team who had less time to prepare, Cunha restored parity three minutes later when he ran on to a through ball from introduced the Dutchman and slid a shot underneath advancing Leeds 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 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 tight schedule.
The Swiss attacker 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 impression, 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 blasted against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a short time, wasted.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be forgiven for hoping the participating nations make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international 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 the club's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in confidence and conviction in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
