Second seed Svetlana Kuznetsova fought back to defeat fourth seed Jelena Jankovic and reach the final of the Dubai Championships.

The Russian recovered from dropping the opening set to win 5-7 6-4 6-3.

Kuznetsova held her nerve in the final set to close out a marathon two-and-three-quarter hour match.

She will meet either Elena Dementieva or Francesca Schiavone (who knocked out top seed Justine Henin in the previous round) in Saturday's final.
