Barcelona produced an excellent performance for their 3-1 win over Atletico Madrid.
Neymar put the hosts ahead after 12 minutes and Luis Suarez doubled their advantage before the break.
Mario Mandzukic pulled one back for Diego Simeone's side after Lionel Messi had given away a penalty, but the Argentine sealed the points for the Catalan outfit late on with a close-range finish.
Afterwards, Messi declared: "We knew it would be a really difficult game and would condition the future.
"They've been tough for us since Cholo arrived there, but we went after them from the start. They are really hard to play against. They've got great players who create great moves. But we controlled them. It wasn't a penalty, but up to that point they'd not got close to our goal."
