Steve Clarke has named his starting eleven for Scotland’s must win Euro 2020 tie vs Croatia.
Stuart Armstrong replaces Billy Gilmour in midfield as the Scots look to make history by qualifying for the last 16 with a win in their final group game.
Three points will guarantee Scotland a place at the knockout stages of a major tournament for the first time in history, but anything less will mean they finish bottom of group D.
The game can be watched live on STV and STV Player.
Southampton midfielder Armstrong is the only change from the 0-0 draw at Wembley on Friday as he comes into a three man midfield.
The rest of the team that earned a point against England retain their place.
The starting line-up is Marshall, O’Donnell, McTominay, Hanley, Tierney, Robertson, McGregor, McGinn, Armstrong, Dykes, Adams.
Billy Gilmour, who starred in his first Scotland game against England, is missing after a positive Covid test.
Attacking options from the bench include Celtic pair Ryan Christie and James Forrest, Newcatle’s Ryan Fraser and Kevin Nisbet from Hibernian, with the Tartan Army knowing one goal could be enough to get them through.
Steve Clarke said: “It was so important to get something out of the game at Wembley, getting that has kept everybody alive. It was important we went to the Tartan Army after it, they never stop supporting the team, they always kept the lads going and all you could hear was Scottish voices singing songs so it was important we acknowledged that fact.
“My message to the tartan army that will be in Hampden tonight is that sometimes football can go against you in a match and that’s when you need the crowd and we will need the Tartan Army behind us from the first minute to last on Tuesday and that will be extremely important for us.
“It’s going tio be a big occasion, basically a cup final for both teams, both teams have to win.
“I have a little feeling that at some stage in the game tactics could go out the window and could become a little bit like an open basketball game end to end as both teams chase the winner.
“It will be a tough game, but I am sure Croatia will expect a tough game from us.”
Croatia also know that a win at Hampden will secure their place in the last 16 and the World Cup finalists have named a strong side including Real Madrid star Luka Modric and Inter Milan’s Ivan Perisic.
Speaking before the game John McGinn said the squad is hoping to give the Tartan Army a result they will never forget.
The Aston Villa star said: “We are feeling good, we need three points to make history, it’s not going to be easy, Croatia are a good team and we know what they are capable of so we will need to be at our best.
“The atmosphere on the first day was one I will never forget. It didn’t feel like there were only 12,000 in here, we hope we can give them a goal tonight and get a result we will all remember forever.”
