The Turkish giants confirmed that Ozil was travelling from London to Istanbul, with Fenerbahce's official Twitter account posted: "Club Statement: Our club is bringing Mesut Ozil to Istanbul to continue the transfer processes."
The 32-year-old is expected to sign a three-and-a-half-year deal, and has told Turkish outlet NTV to confirm the move.
"I am a Fenerbahce fan," Ozil said. "That is why I am very happy to be coming to Turkey with Fenerbahce. I'm very excited. God gave me the chance to wear this jersey as a Fenerbahce fan. God willing, I will carry it with honour and do everything I can for the team.
"Of course, I'm missing a few matches. I haven't played in a match in a while, but I am physically fit, I have no issues."
