Atletico Madrid striker Diego Forlan admits they go into Sunday's derby against Real Madrid as underdogs.
"They may not be playing at their best, but they're at the top and have a big points advantage because they deserve to be."
On his recent scoring drought, Forlan added: "I'm not worried. I could end it on Sunday. It's the same challenge as always, as against any opponent and goalkeeper. It is a game against a great team, one of the best goalkeepers, but the challenge is always the same."
