Match Summary
- Dominic Calvert-Lewin sees a first-half header come back off the post.
- Brenden Aaronson puts the hosts ahead with a low finish in the second half.
- Cunha responds just three minutes later.
- The Yorkshire side continue their longest top-flight unbeaten run since the turn of the century.
The Red Devils' disappointing recent struggles continued at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for the team not suffering even more damage against Leeds.
The Everton loanee directed a first-half effort against the post for the in-form hosts before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against a team who had two days less to prepare, Cunha levelled three minutes later when he latched onto a pass from substitute Joshua Zirkzee and slid a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when Amorim is without four key attacking players due to a combination 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 diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the match, 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 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, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards 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 season.
But without them, Amorim has few attacking options.
He evidently does not have full faith in youngster Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost immediately after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks similar to previous underwhelming signings, lacking in belief and conviction 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 new signing.
Leeds United Breakdown: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as evident as in previous fixtures.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in advanced 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 finding it tough when a mistake opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a wider context for Daniel Farke and Leeds to deal with.
When they endured a poor run of form earlier in the season, many speculated about the manager's future.
Instead, he is now masterminding significant improvement.
The job is not completed yet but gradually, Leeds are getting nearer to achieving their survival.
What Happens Next?
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also entering their FA Cup journey with a Old Trafford tie.
