The 32-year-old, who was the top scorer in Wolfsburg's 2009 Bundesliga title success, revealed the offer from the Dubai-based club had been too good to refuse so late in his career.

"At my age it is time to think of my family, which is close to my heart, and discover something new," he told Wolfsburg's official website.

"I want to take a step forward and also prepare my family particularly well for my life after football."

He added: "I want to thank Wolfsburg for four great years in a magnificent country and at a wonderful club.

"My special thanks go to VfL Wolfsburg, which has provide the most notable moments of my career."

The Brazilian scored 28 goals and was named German Footballer of the Year when the Wolves won the 2009 Bundesliga title.

Last season Grafite, who has been capped four times by Brazil, managed just nine goals as Wolfsburg narrowly avoided relegation.
