Rio de Janeiro: Chile coach Jorge Sampaoli revealed on Tuesday that key midfielder Arturo Vidal is not guaranteed to face Spain in the World Cup Group B showdown between the teams on Wednesday.
The Juventus midfielder underwent knee surgery a month ago and played for only the first 60 minutes of Chile`s 3-1 win over Australia in their opening game on Friday.
"I always said it was very difficult for him to join us here because he had a very serious injury and he had surgery," Sampaoli told a pre-match press conference at the Maracana in Rio de Janeiro on Tuesday.
"However, he managed to play some minutes against Australia and we`ll see how he feels now. He`s been training at a higher pace this week and we`ll see if he can play some minutes tomorrow (Wednesday).
"We analyse his situation every single day. We know he`s recovering now, he feels much better and he`s here because he`s really dedicated and willing to play.
"Arturo wants to play for the national team and we`re very happy to have him here, if that doesn`t damage him."
Victory for Chile could send Sampaoli`s side into the last 16 and consign champions Spain to elimination, depending on the result of the day`s other group game between Australia and the Netherlands.
