Ana Ivanovic has expressed her disappointment following Friday's third-round defeat to Sara Errani at the French Open.
Despite dominating the opening set, the Serbian eventually went down 1-6 7-5 6-3 at Roland Garros.
"It's really disappointing because I felt like I had a game and I was playing really well," the Serbian told reporters. "My serve really let me down."
Number 21 seed Errani will now face Svetlana Kuznetsova for a place in the quarter-finals.
