Real Madrid midfielder Luka Modric has admitted that his team are currently going through "a difficult moment".
Los Blancos landed their third straight Club World Cup at the back end of December and have progressed through to the latter stages of both the Champions League and Copa del Rey.
Madrid have struggled in La Liga this season, however, with Sunday's 2-0 home defeat to Real Sociedad leaving the team down in fifth spot, 10 points off division leaders Barcelona.
Modric has insisted that the European champions must improve individually and collectively as they look to enjoy a successful second half of the 2018-19 campaign.
"Missing goals and more unity on the field. At home, they're scoring goals on us and we aren't scoring many," Modric told reporters.
"We have to sit down, talk and to see what is our problem. It's not normal, it's not just one time, this has happened many times. You have to find solutions, lots of players are not performing at their best.
"I have to improve and assume more responsibility. It's a difficult moment for the club but these things have to unite us more."
Madrid will host Leganes in the first leg of their last-16 Copa del Rey tie on Wednesday night.
