Arda Guler dominated the Turkish Super League last season, helping Fenerbahce finish as close runner-up. He netted six goals and seven assists in his 35 appearances.
Deco is said to be the man pushing Barca to sign the 18-year-old midfielder this summer, according to Sport.
Barcelona have already made enquiries and are well-versed about the player's ability. The Blaugrana have since declared their interest.
Guler is currently valued at €17m, but the Blaugrana could beat down the price by offering to loan back the player to Fenerbahce for one season after completing his signing.
Barca are aware that there is strong interest from other top European clubs for the midfielder, notable of which is Real Madrid.
Barca are quick to spot and sign top talents like Pablo Torre, Pedri and now the Turkish gem is next on the line. Guler could be one for the future like his aforementioned peers.
