Arturo Vidal has cast doubt on his Juventus future after claiming to be unsure if he will remain at the club beyond the summer transfer window.

The Chilean, who helped his nation into the last-16 stage of the World Cup with a group game to spare, has been linked with a move to Manchester United in recent days.

Asked about his future after Chile's 2-0 win over Spain, which saw the defending champions exit the tournament, he told Tuttosport: "Will I stay at Juventus? I don't know."

Vidal, 27, has a further three years on his existing contract with the Bianconeri.
