Barcelona ace Luis Suarez was left frustrated after their 0-0 draw with Athletic Bilbao.

With Real Madrid having leapfrogged their rivals Atletico Madrid with Saturday's derby victory it was imperative for Los Cules to maintain their significant advantage at the summit of the table, but they simply could not break down a tough home defence.

"In the first half we suffered from a lack of communication," he explained in his post-match interview.

"This is something we have to correct, we lost possession and didn't talk to each other.

"We have, though, played a lot of matches and that was a boost for them since they were more rested, but we did create chances."
