Scotland assistant manager Stuart McCall is of the belief that Croatia has enough depth to bring in quality players if they need to rest some of their stars.
Croatia boss Igor Stimac has to deal with the fact that the likes of Luka Modric, Vedran Corluka, Niko Kranjcar and Nikica Jelavic are all on the yellow card tight rope after accumulating bookings during the World Cup qualifying campaign.
The Croatians have already sewn up second spot in Group A but McCall feels they will still want to put in a good showing with their strong squad.
"As a manager you want to go into the play-offs on the back of a good result," the Motherwell boss said.
"There are a lot of key individuals on yellow cards and if they were to pick another one up they would miss a play-off game.
"It depends on the individual. If you look at the likes of Modric, you think, is he a hot-head? Is he sensible enough to think, 'I am not going to get myself in a situation?'
"Then you look at centre-half Corluka. He has to win his headers and win his tackles so it is difficult.
"But if you look at Friday night (2-1 loss to Belgium), they still had a lot of good players on the bench.
"Niko Kranjcar came off the bench to score, Ivica Olic was on the bench and there were other star names like Eduardo so they have a strong squad.
"I am not so sure that making three or four changes will weaken them much with the strength and depth they have."
