Speaking to the club website, Morrison said: There are still parts of my game I need to improve but I think I can get 20 goals next season.
"The one thing that we have to improve is the number of goals we score because we haven't scored enough this season.
"I know I've got a few and hopefully I can get some more before the season finishes but I think I can hit 20 if I get a good pre-season under my belt and get plenty of time to prepare."
