Alexis Sanchez wants strong referee
Chile's Alexis Sanchez has urged referee Howard Webb not to be swayed by pressure in their World Cup round of 16 meeting with host nation Brazil on Saturday.
Chile, meanwhile, were angered by the officiating in their final group appearance -- a 2-0 defeat to Netherlands -- after which Ghanaian referee Bakary Gassama was heavily criticised by Chilean FA president Sergio Jadue.
FIFA has appointed experienced English referee Webb for Saturday's game in Belo Horizonte, and Barcelona's Sanchez said strong officiating was needed for such a pressurised fixture.
"I am very happy to be playing against the hosts, against the best defence in the world, a team with impressive quality -- but what most worries me is the refereeing," Sanchez said. "Well, we will see what happens."
His comments echoed those of colleague Arturo Vidal, who has said he hopes to see "balanced" refereeing on Saturday.
Sanchez said he was confident that Chile, who saw off defending champions Spain in the group stages, could continue to thrive.
"We are going out to win the game," he said. "We came to the World Cup to make history, and that is what we are doing. We beat the world champions.
"I am proud of my teammates -- we are going to show that we can do great things, as we did against Spain."
Meanwhile, Sanchez -- who has been linked with a summer move to Liverpool, Arsenal, Juventus or Atletico Madrid -- welcomed Barcelona's signing of goalkeeper Claudio Bravo, his international captain.
"I was not surprised by the signing," he said. "[Bravo] is the special type of goalkeeper that Barcelona needs. He is very good with the ball at his feet."
