Barcelona star Arda Turan has missed training after picking up a cold according to the Milliyet. Sergio Busquets also missed training after also coming down with a cold.

The reigning La Liga champions take on Athletic Bilbao on Wednesday in the Spanish Cup quarter-final second leg tie. Barcelona won the first leg against Bilbao 2-1 at the San Mames stadium.

Turan is expected to recover in time for the return leg tie and make his seventh Barcelona appearance.

Barcelona have maintained a 100 percent win record since Turan made his debut against Espanyol just over a fortnight ago.

The bearded winger has featured in all six games since starting in five of the games. Barcelona have scored 20 goals and conceded just three with Turan providing two assists and playing in four different positions.

Turan started for Barcelona in the 2-1 win over Malaga on the weekend providing the the highest pass accuracy pulling of 98 percent of his attempted 55 passes.
