It has been reported that Turan, who arrived at Barca last summer but had to wait until January for his debut, had been placed on the transfer list.
That news had alerted that attention of Chelsea, who tracked Turan during his time at Atletico Madrid.
It has also been suggested that the 29-year-old could be open to leaving after managing just nine La Liga starts in the second half of last season.
But now Barca’s sporting director Fernandez has drawn a line under speculation by insisting Turan will not be sold.
Speaking at a press conference, he said: “Arriving at Barca, even if you come from a big club, is not a simple process. You face [getting into a team] a team that is very strong.
“But we expect a lot from him, we have total confidence in him and hopefully he will be decisive next season.”
