“(Poor performance) have recently had to do with my back (injury),” the Basel-based player told Swiss media. “But sometimes with the head, with the self-confidence. Often, everything is interconnected somehow. Success is sometimes easy, but it’s sometimes a science.”

Ivanovic said that looking at previous matches on tape brings back memories but also shows her improving form on certain shots. “I often think that I’m now having a good day. When I watch old videos of me, I realize that my forehand is stronger now. I have more spin on it.

“Before, I hit the ball relatively flat, wondering if it would go in or out. A lot has to do with self confidence and match rhythm. For awhile, I was packing my suitcase almost form the moment that I arrived.

“But when you are winning, you can’t help but want to win more. If you lose the feeling it is slow to build back. But I think I’m on the way.”

Ivanovic is playing this week in the final event of the WTA season, the Tournament of Champions in Bali.
