Rafael Nadal admitted his 6-4, 6-4 loss to Germany`s Alexander Zverev in the Madrid Open quarter-finals on Friday was a "step back" but insisted there were plenty of positives as he plots his way to a 14th Roland Garros title. Nadal has now fallen early in two clay-court Masters tournaments ahead of the Grand Slam in Paris, after going out in the Monte Carlo quarter-finals last month before winning in Barcelona. Even in Barcelona, however, he needed to save a championship point to beat Stefanos Tsitsipas in the final. Nadal is hoping to clinch a 14th Roland Garros title and record-setting 21st major in the French capital next month. "I took steps forward, but when you go up a staircase, there are times when it happens that you take a step back, that`s what happened today," said five-time Madrid champion Nadal. 

"It`s a week where there were a lot of positive things. I`m leaving Madrid with good feelings in general, and the bad one having played a match like today. "Now, what is the goal before Roland Garros? Go to Rome (for next week`s Italian Open) and win, that`s all." Nadal had been hoping to reach the semi-finals of a Masters event for the 75th time. "I had the match under control at the beginning and was playing well for six games, probably playing better than him," said the Spaniard. "Then at 4-2 serving for 5-2, I had a disaster." Nadal continued: "Of course, playing against one of the best players in the world, under these circumstances, with this speed of the court, it`s very difficult."
