Key Moments
- Dominic Calvert-Lewin watches a early header ricochet off the post.
- Brenden Aaronson puts the home side ahead with a low finish in the second period.
- Cunha levels just three minutes later.
- The Yorkshire side extend their best Premier League undefeated streak since the turn of the century.
The Red Devils' poor recent struggles persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
The Everton loanee directed a first-period effort against the woodwork for the confident home team before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to prepare, Cunha levelled three minutes later when he latched onto a pass from introduced the Dutchman and slid a finish underneath advancing home 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 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.
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 the Slovenian striker, 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 contest, also blasted against a post late on.
The draw prolongs Leeds' unbeaten run to seven games, their longest such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a matter of hours, wasted.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on Amorim's options.
It's not that the absent players are the solution to all of the club's problems. After all, they were part of the side that suffered disappointing results earlier in the season.
But without them, the boss has few attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost immediately after his arrival as a substitute.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to 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.
Leeds United Breakdown: Another Step Towards Safety
After memorable victories in their last few home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were instances of typical fervor, but the hostile edge was not as evident as in other encounters.
The home fans were more concerned about their side's inability to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that struck 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.
For a short moment, The home delirious fans thought they were about to secure a rare win against their old foes.
However, there is a wider context for the manager and Leeds 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 improvement.
The job is not completed yet but step by step, Leeds are getting nearer to securing their survival.
What Happens Next?
