Defending champion Novak Djokovic started a new chapter with Andre Agassi in his corner with a straight-sets win Monday against Marcel Granollers in the first round of the French Open.

Djokovic employed Agassi as his coach this month in an attempt to get back to the peak of his powers and the American great sat placidly in the Serbian's box to see him win, 6-3, 6-4, 6-2, on Court Philippe Chatrier.

The second seed has failed to add to his tally of 12 major titles since completing a career Grand Slam at Roland Garros last year and still has plenty of room for improvement on the evidence of his display on Day 2.

Djokovic, the world No. 2 who turned 30 last Monday, will now pick the brains of Agassi before taking on compatriot Janko Tipsarevic or Joao Sousa in round two.

Meantime, also on Monday, Rafael Nadal launched his bid for an historic 10th French Open title with a commanding 6-1 6-4 6-1 victory over Benoit Paire.

The Spaniard, whose last Roland Garros success came in 2014, needed less than two hours to extinguish the threat of the home hope, despite a brief second-set wobble.
