Ahead of the clash in Zagreb, Croatia striker Ivica Olic spoke of how he anticipated winning the game by 'at least two or three goals', and coach Igor Stimac said he was expecting to come up against an 'inexperienced defence'.
The two sides have had differing fortunes during qualification with the Scots still chasing their first win, but Morrison says the comments coming from the Croatia camp will give them an added incentive.
"We're going to use that as motivation. Nobody likes to be disrespectful," he told The Daily Record.
"We know they are a good team but they don't need to go about it the way they're doing it.
"They say in football don't talk, just play."
