Novak Djokovic says Grand Slam trophies and the No. 1 ranking are no longer his priority.

The top-ranked Serb, who has won 12 major titles, says he felt emotionally drained after winning the French Open in June for his first Grand Slam title at Roland Garros and his fourth in a row.

He says he "wants to redefine" his goals.

Djokovic says that before the French Open he "psychologically felt huge pressure and now I'm no longer thinking about the number of titles."

Djokovic has withdrawn from the China Open because of an elbow injury.

The U.S. Open runner-up has had a poor midseason, losing at the Olympics and Wimbledon in the early stages. He has reportedly had physical and personal issues which reflected on his recent results.
