With two assists and a goal off the bench at the weekend, Tony Docherty will have a hard time leaving Michael Mellon out of the starting line-up on Tuesday.
The Burnley loanee is one of several Dundee bodies fighting for a place as they head to Pittodrie with hopes of boosting their top-six charge.
But who would you have on the teamsheet? Pick your side here.

Doug: Could this have been the victory that sets Dundee up a top-six finish? A big three points and a big bite out of our negative goal difference too. The team as a whole really dug in. There was no collapse after Livingston scored their penalty and Michael Mellon already looks like he is as important an acquisition as Owen Beck was before him. More please!
Paul: Great win from The Dee. What we need is some consistency now. We are away to Aberdeen on Tuesday - our fifth away match in a row - and I'd love to see us get a result up there. We have proved the doubters wrong so far. Let's keep it going.
Broughty89: What an amazing job Tony Docherty is doing. Probably our best manager since Paul Hartley. Can't wait for United to be back up next season.

Dundee can learn from how partner club Burnley turned an "ageing stadium" into a Premier League venue, according to John Nelms.
The Dens Park managing director believes the work done by the Premier League side in ensuring Turf Moor was suitable for top-flight football can give the Scottish Premiership side ideas when it comes to developing their new ground.
“Both our organisations, although we're in different tiers, we have a lot of the same issues,” he told BBC Scotland.
“I've seen their stadium, I've gleaned some information that they've done - they have an ageing stadium but they've done some really good things with that stadium that we're going to take and put into the new stadium.
“They have the same mindset that we have and the same ethos of what we want to do. We've spoken to other clubs in the past and it's just never worked out - it's about the people, so that's what was important to us.”
The clubs announced a strategic partnership last week, which will see Burnley advising the Dark Blues on best practice and improvements behind the scenes.
Three Burnley are currently at Dundee on loan, with one of those - Michael Mellon - coming off the bench against Livingston to score and set up two more goals in an impressive debut on Saturday.
“We get great players, players we probably wouldn't be able to afford,” said Nelms.
“We get to develop these players and try to really push them on for Burnley's benefit but at that same time we're getting a quality of player we might not be able to have up here.”
Happy with that performance, Dundee fans?

Let us know your thoughts on today's victory here.
Image source, SNSDundee manager Tony Docherty tells BBC Scotland: "I think we have performed better, but it was a thoroughly satisfactory result.
"In the first half we never quite got to grips with the game - maybe it was the change of shape.
"In the second half, there was a real resilience. I asked my players to stand up today and, my god, they stood up. I'm really proud of them.
"I thought Michael Mellon had an outstanding debut. The kid came on for, I think, 30 minutes and he's got two assists and a goal."

Tony Docherty's side grew into the game after a slow start and never looked like dropping points - even after Luke McCowan's dismissal and Tete Yengi's spot-kick.
It would be easy to pin the performance on Livingston's failings, but credit must be given to a well-oiled team who showed class throughout and were ruthless in front of goal.
Harrison Sharp impressed in goal with numerous fine stops, while the backline and midfield five refused to yield any space to the home side - even with only ten men on the park.

What better way to show your new club your quality than two assists and a goal off the bench. A truly terrific showing from the Scotland under-21 international.
Tony Docherty opts to make a change in goal, with Harry Sharp replacing Trevor Carson.
Midfielders Finlay Robertson, Mohamed Sylla and Scott Tiffoney come in for benched trio Lyall Cameron, Malachi Boateng and Zach Robinson.
There is a place on the bench for new arrival Michael Mellon, who joined on loan from Premier League outfit Burnley on Friday.

Dundee have used their partnership with Burnley to secure the loan signing of striker Michael Mellon.
The 20-year-old shone in League Two in this first half of this season, scoring 13 goals in 22 league appearances while on loan at Morecombe.
Mellon, who came through Manchester United's academy before joining Burnley, has also been capped by Scotland at under-21 level, and is the third Burnley player to sign for the Dark Blues this month, after Dara Costelloe and Owen Dodgson.
"He is a player of such high calibre and a player that we’ve been tracking for a long time," manager Tony Docherty said.
"We are indebted to Burnley Football Club and our partnership with them for helping us bring Michael in when he had so many suitors. We are now seeing the fruits of the partnership with Burnley, as we now have three talented young players from them that I believe will help us this season.
“Michael is a fantastic footballer, he’s not just a goal-scorer, he’s more than that. When you look at his all-round play, he’s strong, he’s quick, he’s got great technical ability and his link-up play is very good. But his biggest quality is his knack of scoring goals."

Dundee striker Zach Robinson says throwing away points from winning positions is "something that has happened too much this season".
The Dark Blues squandered a two-goal lead before losing 3-2 away to Heart of Midlothian in Tuesday's Scottish Premiership encounter at Tynecastle.
"Definitely lessons to be learned," Robinson said. "Today, we have been looking at how to fix that and go forward.
"It is a bunch of things - taking responsibility on the pitch, individual errors, or collectively making sure things don’t happen."
Dundee remain handily positioned in eighth place in the table, with games in hand on the teams above them, but Robinson has warned that they have to learn to hold on to any leads.
"You don’t want to look at the league table too much," he added. "But we believe, if we keep doing what we are doing, improving on what we are doing, we will be in a good place.
"We are a young squad, but it is no excuse to lose leads like we have done this season and it is definitely something we are not happy about. I think, just as a collective, we need to take more responsibility out there."
Image source, SNSAfter winning three consecutive matches against Dundee between January and May 2022, Livingston have since lost each of their last two against the Dee, failing to score in both matches (0-2 & 0-1).
Dundee won their last league visit to Livingston (2-0, October 2023) and are looking to make it consecutive such wins on the road against them for the first time since May 2019.
Livingston have failed to win any of their last six league matches at home (D2 L4), last going on a longer winless streak at home in the top-flight between May and November 2005 (run of nine).
Dundee have only won one of their last seven league games (D2 L4), and could lose back-to-back Scottish Premiership matches for the first time this season, after losing 3-2 to Hearts last time out.
Livingston are the lowest scorers in the Scottish Premiership this season, netting just 12 times from 21 matches and drawing a blank in 12 different matches, more than any other team.

Dundee manager Tony Docherty believes the loan market has helped him build stability at the club after he inherited a threadbare squad in the summer.
The Dark Blues have signed several loanees during the course of the season, and Docherty says he has been able to use them as "building blocks" as he plans for long-term success.
"What you need to do is get stability in your football club first," Docherty said.
"I came in here in the summer and there were only three signed players, so it is important that you build a squad that is robust for the season, but you do it as a foundation and you use it as a building block to move on from that. That is the benefit you can get from bringing in loan players.
"Then you can develop from that; when you want to build your football club you want to do it on the basis of full-time employees. It is part of a process that we are endeavouring to do at the moment.
"And we will keep doing that, we will keep trying to progress the club forward in any way we can."

Dundee manager Tony Docherty has been speaking to the media before his side's Premiership trip to bottom club Livingston on Saturday.
Here are the key lines from his press conference:
On long-serving Cammy Kerr's loan move to Inverness CT, Docherty said it was "difficult" letting him go but says he couldn't guarantee him game time and described him as being "one of the best professionals I have ever worked with".
Docherty says he is still "looking to do a couple of things" in this transfer window, adding that Burnley striker Michael Mellon is "one among many" players they are looking at, describing him as "a fantastic footballer". Did warn a lot of clubs are looking at him.
Docherty was asked if there was any chance Owen Beck could return on loan. He says they "certainly would welcome him back", but it depends what Liverpool's aspirations are for him.
After the midweek defeat to Hearts, Docherty said the first-half performance was "as good I've seen" and thinks his players will learn from the nature of the loss.
On the recently announced link-up with Burnley, and the prospect of some Dundee players eventually heading there, he said there is "no doubt if we continue to develop good young footballers, there is a pathway".
There are no fresh injury worries before the game.

The game was originally scheduled to be played on 2 December but the game was postponed due to a waterlogged pitch at Dens Park.
It was then rearranged for Wednesday, 14 February, but with both clubs out of the Scottish Cup, they have agreed to move the game forward to a weekend date.
Image source, SNSDundee full-back Cammy Kerr has joined Scottish Championship side Inverness Caledonian Thistle on a loan deal until the end of this season.
Kerr has not been a regular starter for Tony Docherty's side this season, and now heads to the Highlands in search of a starting berth.
The 28-year-old had his Dundee testimonial earlier this season, and remains under contract at Dens Park until the summer of 2025.
