Nadal is currently preparing for the MercedesCup in Stuttgart, which has made the transition from clay to grass for the 2015 season.
Having dropped to number ten in the world following a poor clay-court season in which he failed to win a title on the European circuit and saw his French Open title defence halted by Djokovic at the quarter-final stage, the Spaniard is in desperate need of a showing showing on grass to kickstart his season.
With Wimbledon just three weeks away, the 29-year-old has upped his grass-court preparations considerably, and is so focused on practicing that he didn't even watch Sunday's final at Roland Garros.
"I did not watch the match; I was practising," Nadal told the official ATP website. "It’s not the time to think about it today. It’s time to think about practice.
"First time on grass is always hard. I’m going to try my best, practice as much as I can today and tomorrow and Wednesday for my first round match."
Nadal has fond memories of when the MercedesCup used to be played on clay as he won the tournament in 2005 and 2007, but he has conceded that his road to victory will be a lot tougher this year as he has struggled on grass in the past.
The 29-year-old is confident that he will be back to his best sooner rather than later after his rankings drop, and the first step in achieving that is moving on from his defeat to Djokovic.
"I don’t need to deal with (the loss to Djokovic) anymore," he added. "It’s in the past.
"I just have to improve my level of tennis, my intensity on the court. If I can do that, then I am confident I can get back to the highest level."
