The Nigerian captain has finally signed a permanent contract with the Turkish giants where he will be for the next three seasons
The on-off transfer was finally announced on Saturday.
The former Everton defender, who made over 200 appearances for the Toffees in a decade-long stay at Goodison Park, was the first signing that David Moyes made in his Everton career.
Yobo has been on loan at the Turkish giants for the last two seasons where he has won the league and the domestic cup.
The Nigerian defender signed a three-year deal with Fenerbahce, where he has made over 60 league appearances and scored two goals.
Yobo signed for Everton from Marseille in 2002 for £3.5 million and went on to start 182 Premier League matches for the club.
