Forlan, whose last goal for Atletico came in mid-September, is hoping he can end his barren spell this weekend.
"Hopefully. I'm feeling good heading into this derby. I want to recover the happiness of scoring goals. It's not the first time this has happened to me and I need to continue working hard. I know what I have to do continue improving," said the former Manchester United man, who insists his side will not settle for a draw.
"One always goes out to win games, and then is you achieve it or not depends on the circumstances," he added in AS.
"We will try to do everything we can to get the victory."
