Nicolas Anelka completed his �7m move from Manchester City to Fenerbahce after passing a medical on Monday. The 25-year-old French striker has agreed a three-and-a-half year deal with an option of a one-year extension with the Istanbul club.
Anelka arrived by private jet and after passing a medical signed his contract in front of a media circus.
The French striker has now fetched a total of nearly �60m in transfer fees during his career.
Arsenal boss Arsene Wenger paid Paris St Germain �500,000 for his services in February 1997.
The Gunners sold him to Real Madrid in August 1999 for �22m, but after a short, unhappy spell at the Bernabeu, was sold to PSG for �22m in May 2000.
He had a spell on loan with Liverpool but Manchester City paid �13m for him in June 2002, and he scored 45 goals in his time with City.
Fenerbahce's website said: "Agreement has been reached with Nicolas Anelka, following a deal with his club."
The statement added: "The contract is in line with our wishes and principles."
