Spain international midfielder Sergio Busquets has admitted that he and his teammates are under pressure ahead of their World Cup qualifier against France in Saint-Denis on Tuesday.
The reigning European and world champions will head into the Group I encounter two points behind Les Bleus in second place.
"Many teams change their tactics against us," Busquets told Le Parisien. "Sometimes, we'd like to go toe-to-toe with them. It's rare that happens.
"France did it recently, but normally it's our fault if we mess up a game, which goes to show that we're not invincible. If we don't win, it'll be difficult to qualify automatically for Brazil.
"A great nation is going to miss out, but that's the way it is. It often happens with Barca as opponents park the bus. It's frustrating, unjust even. But we're La Roja and the team to beat. When we say 'each game is difficult', it's not just empty rhetoric."
Spain will head into Tuesday's game on the back of a 1-1 home draw with Finland on Friday.
