The 31-year old will take the second marquee spot on the sky blues' squad, replacing Alex Brosque.

Nicknamed 'Bobo', the Brazilian striker leads the goalscoring record for the Turkish giants Besiktas, having scored 97 goals in 222 games for the 14-time Super-Lig Champions.  He has also had spells with Kayserispor in Turkey, and Gremio, Cruzeiro and Corinthians in Brazil.

Bobo joins the Sky Blues from Gremio.

"I'm very happy to be joining to Sydney FC, it is a massive club with a big chance of winning silverware this season," he said in a statement.

"I believe I am coming to Sydney FC to win trophies and I will not be satisfied until we have achieved that."

Bobo will link up with former team mate Filip Holosko. The pair played together for three seasons in Istanbul.

"I have heard a lot about the fantastic Sydney FC Members, especially the Cove and the brilliant atmosphere they create. I can't wait to play in front of them," he said.

Coach Graham Arnold believes the 1.86 metre centre forward will be a crucial addition in the club's quest for trophies.

"Bobo is proven goalscorer with a great pedigree and I'm extremely excited to begin working with him," he said.

"He is a very natural striker, can score with either foot and his head and will be a major threat up front for us this season.

"His record speaks for itself, he has scored many goals in the top league in Turkey, he is clinical in front of goal and I think once he is up to speed, he is going to be a very exciting player for Sydney FC.

"I'm happy our squad is now looking very strong with still more than a month to go until the start of the season."

Bobo has played 13 times for Brazil's under 20s scoring seven goals and will become the club's second international marquee for this season.
