Real Madrid midfielder Wesley Sneijder claims Barcelona are fortunate to hold a 12-point lead at the top of La Liga.
Sneijder believes Madrid are more of a team than their great rivals, who have been heavily reliant on individual performances to take a grip on the title race.
"The difference at Barcelona is (Lionel) Messi," Sneijder said. "We are a team and they are individuals.
"They do have a lot of quality and this season they have a great team. But they are also lucky, as they showed against Racing the other day (when Messi scored twice).
"This season they are having the luck that we had last term because there are moments when they do not play so well, but they do have great individuals and luck."
Sneijder admits that he is yet to return to his best form following a three-month spell out with injury following last summer's European Championships.
The Dutch international told AS: "I am not happy because I am not playing to the level I want to. I know that I can improve and that I have more quality than I am showing now."
