Scotland boss Alex McLeish insists his squad understand the significance of beating Israel tonight and is confident they will rise to the challenge.
Victory at Hampden will ensure the Scots finish top of League C, Group One and move to within two ties of qualifying for the Euro 2020 finals.
A draw or a defeat and the Scots would fail in a three-team group comprising a team ranked 60th (Albania) and 91st in the Fifa world rankings.
Anything but three points would also pile more pressure on McLeish so early in his tenure as national manager.
It is win or bust.
McLeish reckons his threadbare squad, hit by a spate of injury call-offs and withdrawals, can deliver – because he has seen it in their eyes.
He said: “It is a huge game for us and there is no doubt about what is ahead if we win.
“I don’t need to remind my players of that as they are under no illusions about how big a game it is.
“They are showing the body language I would like to see from a team going into such an important match.
“We have home advantage and a very good opportunity to do this.
“And these players can do this.
“Confidence is very high with the boys – I can see it in their eyes.”
Scotland will progress to the play-offs against similar standard League C opponents with any win against Israel.
Victory tonight would also elevate Scotland from League C to League B for the next Nations League.
Anything less and Andreas Herzog’s Isreal will reach the four-team Nations League play-offs in March 2020.
Hopes of topping the group were rekindled by a comprehensive 4-0 away defeat of Albania on Saturday.
McLeish said: “We took on a huge game at the weekend after the Israel disappointment (2-1 defeat in Haifa) and absolutely nailed it.
“Players will always try to play at the best level they can. If every one of my players perform at the best level they can I would be positive about the outcome.
“I said that to them before the Albanian game.”
Scotland must win tonight because Israel hold the upper hand in head-to-heads having beaten McLeish’s side 2-1 in Haifa last month.
Lessons have been learned ahead of the return in Glasgow.
McLeish said: “You have to learn from defeat, about what happened and how the opposition did that to you.
“Nobody likes to lose but when you do you have to show resilience and work hard to put that right.
“We did that in the Albanian game with a win and fantastic performance from the players.”
McLeish’s preparations for the Nations League double header suffered a succession of withdrawals due to injury. West Ham’s Robert Snodgrass and Crystal Palace’s James McArthur both asked not to be considered.
McLeish insists there was little disruption to his starting XI.
“I had the team in my head maybe three or four days after the Israel game,” he said.
“I had the team I wanted to play in Albania and against Israel.
“I haven’t lost any of those players except for three. So it has not changed that much.”
Aberdeen centre-back Scott McKenna is set to earn his eighth cap and will anchor the defence.
The 22-year-old will link up with Hamburg’s David Bates who made his debut in Albania. McKenna’s centre-back partner at club level, Mikey Devlin, was in contention for a debut cap with a start against Albania but had to withdraw with a foot injury sustained in training. McLeish praised the partnership of McKenna and Bates who played together for the first time.
He said: “It was a huge night for David Bates. I spoke to him before it and he was cool.
“It takes personality to come into a first cap like that.
“He had a really solid, sound debut. David worked well alongside Scott McKenna and they dovetailed together well.”
