Morrison left Lazio for OSK last month.
Teammate Tom Pettersson told fotbolldirekt.se: "No, he's an incredibly nice guy. One had a picture of him that he was a problem player, but I've noticed nothing.
"Ravel is funny and an extremely nice guy towards everyone. He has been through things that we can only dream of but there is nothing you notice. It might be good for him to come here and just focus on the football.
"When he has the ball he is a superstar. With the ball at his feet he is a level above us others. Then he hasn't played matches for a while and needs to get started. But I've seen enough. His play with the feet and intelligence he shows up ... people will notice when he is in shape, if I say so."
