Boos ring out for Pique
The game marked Barcelona's first visit to the capital since the Catalan independence referendum on 1 October, which was opposed by Spain's national authorities.
Atletico fans waved hundreds of Spanish flags inside the stadium and booed every touch by Barcelona and Spain defender Gerard Pique, who had given his public support for the referendum.

Messi, who scored a hat-trick in midweek as Argentina dramatically qualified for the World Cup, exchanged passes with Suarez in the penalty area, but his low shot was deflected into the side netting.
Antoine Griezmann forced two excellent saves from Marc-Andre ter Stegen in the opening 10 minutes as Atletico set the early tempo, before they took a deserved lead.
Barcelona grew into the game in the second-half with Suarez and Messi forcing saves from Jan Oblak but the Slovenia goalkeeper could not keep out the Uruguayan's equaliser.
