 Novak Djokovic has described meeting Rafael Nadal at Roland Garros as the biggest challenge anyone can have as they prepare to meet in the last four of the French Open. Djokovic made the semifinals by beating Italian Matteo Berettini 6-3-6-2-6-7-7-5 in a match that began with spectators but ended in silence. The contest was halted in the final set so the crowd would leave to comply with French quarantine regulations. Djokovic and Nadal have met 57 times, with the Serb leading their series 29-28. We are going to face each other another time. We had some battles over the years in this court. Last year he just dominated the finals against me. Obviously different conditions are going to be played. On Friday it was the case in the finals of last year so I'm hopefully going to be able to perform at a higher level than I have in the first two sets in the last year's finals. The quality and the level of tennis that I've been playing in the last 3-4 weeks on clay, in Rome, Belgrade and here is giving me good sensations and feelings ahead of that match. I'm confident I believe I can win otherwise I wouldn't be here and let's have a great battle.
