I believe he is playing for a greek club, olympiacos -

A quick google search should help out with this though

At the time he moved, I believe he said he wanted a team where he could play in the first team and that had a chance to go for the one thing he doesn't have - champions league title. Am sure money had a part in it - He always wanted more money and few clubs were willing to part with it for him.
Of course, that took him to greece, which in my opinion has virtually killed his international career.
I hope this helps,
