Set pieces are a particular concern for the Brazilian...
So far this season Madrid have conceded four goals in three games. It has mattered little however, as they have scored eleven and, ultimately, won all three fixtures.
The Brazilian insists, however, that they are looking to eradicate the mistakes that have lead to the four goals conceded.
"We have been weak in defence for these four goals, and we are trying to improve it," Marcelo told a press conference.
With regard to the continual comparisons between Los Merengues and Barcelona, Marcelo insisted that he is keen to focus on his team.
He added, "I just look at Madrid. To win something we must work very hard and that is what we are doing."
