Moscow: Former World No.1 Ana Ivanovic's career has struggled at times since she won her only Grand Slam title in Paris in 2008.
Participating in the Kremlin Cup here, she said that her own nerves have been a tough opponent before matches. Ivanovic also spoke about her problems with confidence and consistency.
"Before every match you are nervous a little bit but it's good in a way because sometimes when you lack those nerves you don't perform well. You're quite flat. Sometimes it's overwhelming. You have to find the balance to breathe through it but it comes with confidence. Once you're confident, it's easier to deal with everything," said Ivanovic.
