Scotland face the joint Group A leaders at the Stadion Maksimir looking to win their first match in the World Cup qualifying campaign, having already bowed out of the comeptition.
Croatia striker Ivica Olic claims the home side are looking to "win by two or three goals" in order to boost their goal difference while former national team boss Miroslav Blazevic reckons Scotland "will go back home with five goals in their net."
Morrison believes the comments are disrespectful to the Scotland squad, but he expects the team to react on the pitch.
"We will put it to the back of our minds at this stage but once the game comes on Friday we will try to use that to motivate ourselves," Morrison said.
"It is not nice but we are concentrating on our training week. We are doing double sessions and working really hard.
"There are a lot of new players trying to get used to each other and so we are just going to concentrate on our game and let them deal with themselves."
