Coach Zeljko Krajan will begin working with former No. 1 Jelena Jankovic starting Tuesday in Moscow, where Serbia is scheduled to play its Fed Cup semifinal tie against Russia, TENNIS.com has learned. Krajan just split with Dominika Cibulkova after working with her for almost two years. Known as an intense coach who encourages his students to be extremely aggressive, Krajan also brought Dinara Safina to No. 1. Jankovic recently ended a short coaching trial with former UNLV standout Henner Nehles. Currently ranked No. 18, Jankovic has not won a tournament in more than two years.—Matt Cronin
