Two-time Wimbledon winner Rafael Nadal is going into the 2017 Wimbledon Championships happy with how his ageing body is holding up.
The 30-year-old has had issues with tendonitis in his right knee for nearly a decade and has often been the reason for withdrawing from tournaments.
The grass court season is tougher on the knees due to the balls lower bounce and Nadal has opted to skip the warm-up tournaments in order to protect his body.
"I know that my knees have hindered me a lot on grass in the past few years," revealed the 15-time grand slam winner on atpworldtour.com.
"They stopped me from competing at the maximum level. The switch to grass has been progressing well and the test will come later, but I am confident that my knees are going to hold up. Then the results as always depend on many factors."
The Spaniard has not enjoyed the best run at the All England club and he blames his ageing knees for the poor results. This year, he hopes to change that.
"In 2014 I made the fourth round and it was my best year since reaching the final in 2011," added Nadal.
"Since then I've had many problems with my knees. In 2012 and 2013 it was really bad and then in 2015, my knees were fine, but I felt bad for many other reasons. Last year, unfortunately, I broke my wrist right before Wimbledon. It's been a few years that I haven't been able to compete well and that is a disadvantage compared to those who arrive here having done well year after year."
While Nadal has missed the traditional lead-up tournaments, he has been putting in the time on the practice courts, reportedly with rising star Alexander Zverev.
