Arsenal midfielder Gilberto Silva has completed his move to Panathinaikos.
The 31-year-old passed a medical and signed a three-year deal after Arsenal accepted an offer of around £1m.
"I came to Greece because I have big ambitions, it's very important for me to be able to continue to give my best. I couldn't say no to the offer."
Gilberto was keen to join up with Panathinaikos boss Henk ten Cate, who left his post as Chelsea assistant coach at the end of last season.
"I'm sure we will qualify through to the group stages of the Champions League," added Gilberto. "I'm exited about being a Panathinaikos player."
The 31-year-old has followed AC Milan signing Flamini and Barcelona recruit Alexander Hleb out of the Emirates.
