Match Summary
- Calvert-Lewin sees a early header ricochet off the upright.
- Aaronson puts the home side ahead with a low strike in the second period.
- Cunha levels just three minutes later.
- The Yorkshire side extend their best top-flight undefeated streak since the turn of the century.
The Red Devils' poor run of form continued at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more damage against their old rivals.
The Everton loanee headed a first-half attempt against the post for the confident hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
However, against opponents who had two days less to recover, Cunha levelled three minutes later when he latched onto a pass from introduced Joshua Zirkzee and slid 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 the manager is without four key attacking players due to a mix of injury and national team commitments.
Not that the hosts to sympathise with that given their own lack of preparation time.
The Swiss attacker 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 struggling to make an impression, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also fired against a post in the dying moments.
The draw extends Leeds' unbeaten run to seven games, their longest such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the participating nations make a swift exit.
Existing injuries to captain 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 United's problems. After all, they were part of the side that experienced poor results earlier in the season.
But without them, Amorim has limited attacking options.
He clearly does not trust youngster Shea Lacey or the seasoned 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 three goals in recent outings, and others operating out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
