The Wellington Phoenix have equalled their club record of seven matches unbeaten.

They did it by grabbing a pulsating 3-2 win over the Western Sydney Wanderers at ANZ Stadium in Sydney on Tuesday night - their first win over the Wanderers since 2016.

Phoenix striker Roy Krishna scored two goals in the final 10 minutes to earn his side the win, which pushes them into fifth, seven points ahead of seventh-placed Newcastle Jets.

It was the first time the Phoenix have gone seven matches without a loss since Jan 4, 2015, a season when they went on to finish fourth after briefly topping the table late in the season. They will look to break that record against the winless Central Coast Mariners at Westpac Stadium on Saturday night.

The only change to either starting XI was ​Michal Kopczynski in the Phoenix's central midfield of the suspended Mandi in midfield. Newly-signed Irish striker Cillian Sheridan was on the bench for the Phoenix.

​The Wanderers suffered a major blow when losing influential German midfielder Alexander Baumjohann to a hamstring injury in the first six minutes, replaced by Nick Fitzgerald.

The Wanderers were awarded a penalty in the 14th minute, but referee Jonathan Barreiro changed his decision after reviewing a replay at the behest of the Video Assistant Referee.

Fenton slid in on Bruce Kamau deep on the left side of the box. Kamau went to jump over Fenton, but dragged his feet. There was no contact until Kamau was almost already on the ground. Barreiro adjudged there to be no penalty, and also found Kamau had not taken a dive.

Alex Rufer picked up his fifth yellow card in the 25th minute, meaning the Phoenix will be without their two started holding midfielders against the Mariners. Mandi has an appeal to be heard on Wednesday night for his three-match ban, but the best case scenario there is it gets reduced to two matches and he's back, with Rufer, for the away game against Melbourne Victory on January 20.

Krishna hit the post in the 33rd minute. Sarpreet Singh caught the Wanderers defence napping with a quick freekick which sent the Fijian through on goal, but his toe-poke finish rattled the left upright.

Louis Fenton did open the scoring three minutes later with his second goal of the season. Again, Singh was the creator, playing a deft scoop onto Fenton's chest, with the right wing back bringing it down well and finishing expertly past a stranded Vedran Janjetovic.

But the Phoenix conceded a soft equaliser in the 43rd minute as Hamill rose highest to head home from a corner which goalkeeper Filip Kurto came to punch, but got nowhere near.

The Wanderers lost Spanish striker Oriol Riera to injury immediately after the goal, replaced by new signing Kwame Yeboah.

After halftime, the Wanderers had two good chances to take the lead via shots inside the box from Kamau and Jordan O'Doherty, but the former fired tamely at Kurto, while the latter scuffed his shot wide.

The Phoenix found their feet in the half soon after, with David Williams testing Janjetovic with a strong shot from the edge of the box after a good one-two with Rufer in the 57th minute.

There was more controversy one minute later when Yeboah gave Rufer a short-arm jab to the small of the back, although it was more a love tap than a punch. Yeboah was shown a yellow card for the incident.

Sheridan made his debut in the 63rd minute, replacing Williams. Thirteen minutes later he flashed a blistering left-foot shot just over the bar from the edge of the box, giving a brief glimpse of what he might be capable of in a Phoenix shirt.

Kurto made up for his error on the Hamill goal by coming up with a good save to deny Yeboah one-on-one with 10 minutes to go.

Krishna put the Phoenix ahead in the 82nd minute through a counter attack. Sheridan was right in the mix, playing a great 30-yard through ball to Krishna. He beat an on-rushing Janjetovic to the ball, rounded him and then lifted his shot from a tight angle over Hamill and into the net.

But two minutes later the Phoenix conceded from a corner again. The ball somehow made it through a sea of bodies to Keanu Baccus at the back post, who took one touch before hammering his finish into the roof of the net.

As rain started to fall, Krishna ended the dramatic match in the 89th minute by scoring a header at the near post after beautiful buildup play down the right from Rufer, Sheridan and substitute Max Burgess, the latter putting in a delightful whipped cross which invited Krishna to slam it in.
