But according to Spanish paper Sport, Turan’s future with the Catalan giants is far from certain.
The report suggests that should a big money offer come in, then Turan could well leave.
The 29-year-old was on Chelsea’s radar last summer when he was at Atletico Madrid and came close to moving to Stamford Bridge.
Should a deal come off, Diego Costa would be pleased to have a familiar face around the club.
Turkish clubs Galatasaray and Fenerbahce have also been credited with an interest.
Chelsea will be hoping for a strong start to their Premier League campaign next month, after they began the last one poorly and finished in 10th spot.
