The Uruguayan has been perhaps the biggest disappointment in a poor campaign and he is aware of the problems.
"I am very happy at Inter. It has been a difficult season due to the injury and the moment the team is going through," Forlan told Sky Sport Italia.
"In my career I have been through difficult moments before. You have to understand where you're going wrong and work to make sure things change. Since I have been at Inter, you have not seen the real Forlan.
"I take it one game at a time, as I always have done. I feel that I can do well and will try to do better every match. If I play well then of course I am happy, so right now I'm not happy."
