Barcelona hold a 12-point lead at the top of La Liga.
“The difference at Barcelona is (Lionel) Messi,” Sneijder told AS. “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.”
