The world's top two players, Justine Henin of Belgium and Ana Ivanovic of Serbia, will play at the Qatar Telecom German Open in Berlin in May.
Henin has won this $1.34-million claycourt tournament three times in her career, in 2002, 2003, and 2005. Ivanovic was a champion last year, beating Svetlana Kuznetsova after being a set down.
In addition to Henin and Ivanovic, several more of the world's top 10 players are expected to participate in the Tier I event.
"The 2007 tournament was one of the best events throughout the world with
eight of the ten top ten players competing" said Sheikh Mohamed Bin Faleh Al Thani, President of the Qatar Tennis Federation on Wednesday. "I assume that such strong entries will again take part at the 2008 Qatar Telecom German Open."
