Real Madrid defender Pepe had no problem with the jeers of home fans during defeat to Atletico Madrid.
Real lost to the defending champs 2-1 at the Santiago Bernabeu.
Pepe remarked: "We work on everything. Maybe we don't have enough concentration in the set pieces, but we have to keep working and ask the fans for their support, because we need them now more than ever. We have to be strong and we have to be a bit more together to fight for everything."
"We have to pick ourselves up and fight. We have a great group, with a lot of quality. I didn't notice any whistling but if the fans whistled then they're right, that's why it's such a great club."
