Jovanovic joined Liverpool from Belgian side Standard Liege in the summer.
“I am feeling much more positive,” said Jovanovic. “If I play bad, I will admit it and I will not be happy but I am at Liverpool and that means I will always, always give my best for this team.
“I was happy with how I played against Birmingham but I know I can do better.
“I am disciplined and trying to build an understanding with the other players.
“I am not in the best form and I can play better than I have shown so far. But I know I can score goals and make assists for this team. I am sure I can.”
