I remember players like Hagi, Drogba and Sneijder in Galatasaray, Roberto Carlos in Fenerbahce, Cissé in Panathinaikos or Rivaldo in Olympiacos. I imagine it would be comfortable living, great weather, great food, he would be adored like a God in Turkey or Greece and he would have a chance to play UCL football.
Otherwise I think it would be very smart PR to do a world tour ending of his career. He should just copy paste David Villa who had a very nice end to his career. Of course you could add one year in Arabia to complete the list below.
Melbourne - 4 games, 2 goals, 0 assists
New York City FC - 126 games, 80 goals, 21 assists
Vissel Kobe - 29 games, 13 goals, 2 assists
