The Juventus star says he has recovered from his minor knee surgery last month and can't wait to take on the reigning world champions on Wednesday
The Juventus star was a doubt ahead of the tournament after undergoing minor knee surgery last month but played an hour of his side’s 3-1 victory over Australia in their World Cup Group B opener last week.
And the 27-year-old has confirmed he is ready to line up against the reigning world champions in Rio.
“[Playing at the Maracana] makes it one of those matches you dream about,” he told Fifa.com.
“There’s an atmosphere in a stadium like that, [with] the fact we’re playing Spain, and knowing that if you win you’re going to qualify from one of the toughest groups in the World Cup.
“[My knee is] fine now. I’m pleased because I made a very quick recovery.
"I thought it was going to be a lot harder for me. Luckily, I made the team for the first match… I hope to show how good I feel in these [upcoming] games and how much I can help the team.”
Jorge Sampaoli’s side will provide a very different type of opposition for Spain, who have become accustomed to the opposition sitting back and looking to hit them on the break.
Chile, however, are stylistically similar to Vicente Del Bosque's side and will seek to control the play with what Vidal admits can be a high-risk method.
“Some say we take a suicidal approach. We press very high up the pitch,” he said.
“We try to stop other teams from playing and win the ball back as high up the pitch as possible. And when we’ve got the ball we start to play and make the opposition run, which is a good way of finding out if they have same level of intensity as we do when we don’t have [the ball].”
Chile complete their group campaign against the Netherlands in Sao Paulo on June 23.
