The Scottish League Cup produced a flurry of results on Tuesday, with several clubs securing places in the last eight of the competition. Celtic comfortably booked their quarter‑final slot with a 4‑0 triumph over Dundee United at Tannadice Park, while Aberdeen dispatched Dundee 3‑0 at Pittodrie. In the lower tiers, Kilmarnock edged Ayr United 3‑2 after a dramatic comeback, and League One side Ross County produced a surprise 2‑1 victory over Dunfermline to claim the remaining place. Below is a detailed recap of each match, the key moments and the players who made the difference.

**Celtic – 4‑0 win over Dundee United** Celtic arrived at Tannadice Park with the intention of making a statement, and they delivered a dominant performance that left little doubt about their intentions for the rest of the tournament. The first half opened with a well‑taken corner from Benjamin Nygren that was met by Auston Trusty, whose header found the back of the net.

The goal set the tone, and the Colombian forward Camilo Duran, playing his first match for the Glasgow giants, added his maiden Celtic goal shortly after. Duran's finish came from a clever movement inside the box, capitalising on a loose ball after Trusty's header.

The second half saw Celtic continue to press. Sebastian Tounekti, a young talent eager to make his mark, struck a low drive that curled into the far corner, further extending the lead.

Nygren, who had provided the earlier assist, completed his contribution with a well‑placed shot from the edge of the penalty area, sealing a comfortable 4‑0 victory. New signings Mika Baur and Haissem Hassan were introduced as substitutes, gaining valuable minutes ahead of Celtic's upcoming Champions League qualifier against LASK at Celtic Park.

**Aberdeen – 3‑0 win over Dundee** At Pittodrie, Aberdeen displayed a clinical edge that saw them cruise past a struggling Dundee side. Captain Kevin Nisbet was the standout performer, netting a brace in quick succession.

He opened the scoring in the 51st minute, exploiting a defensive lapse to slot the ball home. Just twelve minutes later, Nisbet doubled his tally, this time finishing a well‑worked move that left the Dundee goalkeeper stranded.

In between Nisbet's goals, midfielder Mitchy Ntelo made his debut for the Dons and celebrated by finding the net himself, providing a third goal that cemented the 3‑0 scoreline. Dundee's hopes were further dented by the loss of their captain and forward Simon Murray, who suffered a knee injury early in the second half and was forced to leave the field. The injury not only weakened Dundee's attack but also disrupted their morale, allowing Aberdeen to control the remainder of the match and secure a place in the quarter‑finals. **Ross County – 2‑1 upset over Dunfermline** League One outfit Ross County produced one of the tournament's biggest surprises, overcoming Scottish Championship side Dunfermline Athletic in a tightly contested encounter.

The match remained dead‑locked until the second half when Liam Lindsay gave County the lead with a composed finish after the break. Dunfermline responded quickly, with Allan Oyirworth equalising just ten minutes before full‑time, restoring parity and setting up a tense finale.

The decisive moment arrived in the 85th minute when Richard Chin, a rising star for Ross County, struck a powerful shot from inside the box that beat the Dunfermline keeper and restored County's advantage. The goal proved to be the winner, sending Ross County through to the quarter‑final draw and marking a memorable night for the club and its supporters.

**Kilmarnock – 3‑2 comeback win over Ayr United** Kilmarnock entered the tie against Ayr United under pressure, having suffered back‑to‑back defeats in the league. The match started poorly for the Ayrshire side as Owen Stirton gave Ayr an early lead with a well‑timed volley. However, Kilmarnock responded swiftly; Joe Hugill levelled the score with a crisp finish, restoring balance to the contest. The dead‑lock was broken when Ross Taylor unleashed a sublime strike that stunned the home crowd, putting Kilmarnock ahead.

Ayr United, refusing to surrender, fought back and found an equaliser through Michael Schjonning‑Larsen, who showcased impressive solo dribbling before slotting home a low effort. With the score at 2‑2 and the match heading toward extra time, the drama reached its climax. In the dying minutes, Nicky Clescenco demonstrated composure beyond his years. After Ayr goalkeeper Harry Stone mishandled a deep cross, Clescenco calmly dinked the ball over the keeper, securing a dramatic 3‑2 victory for Kilmarnock.

The win not only halted their recent slump but also propelled them into the quarter‑finals, where they will look to build on the momentum generated by this thrilling comeback. Overall, the round of 16 produced a mixture of expected results and surprising upsets, setting the stage for an exciting quarter‑final phase.

Celtic, Aberdeen, Ross County and Kilmarnock will now turn their attention to the upcoming draw, hoping to continue their cup runs and, for some, to chase the elusive trophy that has so far eluded them this season.
