Balotelli has been involved in several bust-ups with City boss Roberto Mancini with the striker's antics upsetting his fellow Italian.
Marwood believes Balotelli should be following in the footsteps of some of his team-mates by setting a good example to the young players coming through at the Etihad Stadium.
Asked what kind of role model Balotelli represents, Marwood is quoted as saying in the Sunday Mirror: "I think that it's important to make a good example.
"I think - and we all know who we are talking about - that you will get people within the system who do not show the right values and the right behaviour.
"In the main, we have a fantastic group of players here.
"I look at [Pablo] Zabaleta, I look at [Vincent] Kompany, I look at Joe Hart, Gareth Barry and Joleon Lescott.
"I think we have a lot of players who can behave in the right way.
"You just have to make sure that they are the role models."
