United were edging things in the early stages of the first half, but the home team, a bit against the run of play, went ahead on 90 minutes.

Impressive work by Olusanya, and he set up Armstrong to finish coolly and calmly into the bottom corner of the net.

This tipped the balance of play in favour of the Dons.

Aguiar was booked for a tackle on Ola Sanja a couple of yards outside the box.

And Nisbet's free kick came off the wall and behind for a corner.

United with a couple of changes at the interval.

It started the second half well.

smartly finished from across on the right hand side but the celebrations were quickly cut short by a flag for offside and that decision was backed by VAR Waters fired over from a tight angle and Mitov saved from Chavez close range shot as the visitors pushed hard for an equaliser there were loud appeals for a united penalty when Dolcek went down in the box but again

The VAR panel said no.

The Dons were looking strong defensively though and started to threaten an attack.

Ola Sanja had a shot deflected away from goal and also lashed over after frames cross picked him out.

The striker working very hard but lacking composure.

The Tangerines were down to 10 men after Aie's second booking for fouling Ola Sanja.

That was 84 minutes in but the Dons made it 2-0 through that man Ola Sanja.

Four minutes after that, 88 minutes on the clock.

Cameron with a great shot from 20 yards.

Richards managed to parry it, but the striker pounced to make it 2-0 to Aberdeen.

So a good day at the office for the Dons.

They had to weather a couple of storms, but they just about deserved the three points in the end, which makes them mathematically safe now in the top flight.

They finished Aberdeen 2, Dundee United 0.
