Midfielder Gilberto has completed his move from Arsenal to Panathinaikos.
The Brazilian, a former Gunners captain, has passed a medical and signed for the Greek club.
Panathinaikos president Nikos Pateras met Gilberto's representatives last week and thrashed out a deal after Arsenal accepted an offer of around £1million to bring to an end a six-year stay with the Gunners.
Gilberto revealed a 'hunger for titles' and the chance to work with Henk ten Cate were the motivating factors for his decision to sign a three-year deal with the Athens club which makes him the highest paid player in Greek football.
'I'm hungry to win more titles,' said Gilberto after penning his contract. 'I came to Greece because I have big ambitions, it's very important for me to be able to continue to give my best. [Henk] ten Cate is a coach I know from his time at Chelsea and I'm looking forward to working with him.
'The people here at Panathinaikos made the decision to come here very easy, I couldn't say no to the offer from the club.'
Gilberto was mobbed by around 1,500 Pana fans at Athens' Eleftherios Venizelos airport when he arrived in the Greek capital last night.
'I'm sure we will qualify through to the group stages of the Champions League and I'm exited about being a Panathinaikos player.'
Arsenal will receive a fee of just under £1million for the player, who will reportedly earn nearly £6million over the duration of his contract, making him by far the best paid player in the country.
