Martins told Kick Off: “It’s always good to score goals and for me, it is important to improve every season.
“I scored 17 goals last season so this season maybe I should be looking at doing better than that. Twenty goals is possible and I hope I can do that.
“Both Viduka and Owen are great players and it shows that the manager is serious about achieving something this season. But I want to play all the time and as long as I am scoring goals, I think I can make it hard for him not to play me.
“Even when I am not scoring, I can make myself a problem for the other team and allow my team-mates to score.”
