In the semifinal of 2015 Monte-Carlo Rolex Masters, two great players from the Big-Four Club squared off against one another on Saturday for the 43rd time and first since 2014 Roland Garros final. It was always going to be the mind game more than tennis skills on court. Finally, Novak Djokovic prevailed over Rafael Nadal despite the Spaniard playing aggressive tennis early in their match. The Serb improved his winning streak to 16 matches and stayed on course to take his fourth ATP 1000 Masters
