Former Scotland defender Willie Miller says Gordon Strachan should go for strength against Germany this evening.
The world champions are at Hampden for the crucial Euro 2016 qualifier, with the Scots languishing in fourth in Group D.
"Scotland are going to need some physically at set pieces," said Miller.
"The Germans are a physical team, with Thomas Muller coming off the wings we need to make sure that we've got strength there."
Scotland go into the game after a disappointing 1-0 defeat in Georgia on Friday, with just three games remaining in their bid to qualify for the European Championships in France next summer.
And Miller expects Strachan to make changes.
"That game's in the past, it wasn't our best performance that's for sure," Miller told BBC Scotland.
"We've been playing extremely well and there's been a lot of plaudits. If we turn in the same type of performance in Georgia against the Germans they will beat us and beat us comfortably. But we're far better than the performance against the Georgians.
"I think James McArthur is playing extremely well so he must have a case to put forward.
"(Ikechi) Anya or (Steven) Naismith didn't produce too much in the game over in Georgia and these are two that Gordon will be looking to replace. James Forrest could come in as well.
"He will make changes, you've got to make that kind of statement."
Not many expect Scotland to pick up anything against Germany, though Strachan has admitted his side need at least a point to keep alive their hopes of qualifying automatically.
Miller says a good performance is essential to lift the side ahead of their final two games at home to Poland and away to Gibraltar next month.
He said: "You're at home, the world champions come calling. It was a difficult game over in Georgia, the team have taken a fair bit of slagging off, the manager as well. They've just got to accept that.
"But this is a great opportunity to put that right. It doesn't come any bigger than Germany at home in such a crucial game, and I think any kind of result is a good one for Scotland looking forward to the Poland game.
"There's big reputations in the other team, you've got to make sure you don't take these reputations on board, it's just another player that you're taking on.
"It's an important game in terms of performance. I don't know if it's an important game in terms of a result, but a result would be fantastic, a stepping stone to the Poland game, and we've got to win the final two games."
