Real Madrid wing-back Lucas Vazquez says form goes out the window in the Madrid Derbi.
Real Madrid meet Atletico Madrid this weekend.
Vazquez said, "It's different, they are special matches that are marked in red on the calendar.
"We always like to win for ourselves and for the madridistas.
"We have to play a game like in the first round, attacking and defending together and playing as a team to create favourable scoring situations."
