Real Madrid defender Sergio Ramos rates Diego Forlan as Atletico's danger man for tonight's big derby.
Real need victory to leapfrog Barcelona back to the top of the table.
Ramos said: "I've always had a special appreciation of Forlan because I consider him one of the best strikers, a hard worker.
"He is a player who always can score goals, although his first effort is to help his teammates."
