The issue first arose back in 2005 which was revealed by his uncle and coach Toni Nadal recently. His other coach Carlos Moya was very open about the confusion within his team as to how to proceed admitting they are not sure. Former tennis professional and tennis analyst Mats Wilader shared his thoughts about hte matter.
He said:
“I am very sad and very worried but I do think he [will] keep coming back until he no longer can. At the moment the will to play is still there. The era of winning may be over, but the era of filling stands with fans is still alive. There are a couple more years of it.”
For Nadal quitting is and never was an option. The calling card for Nadal has been his fighting spirit which saw him carve out a legendary career despite facing many issues and adversities early on. It's something many noted and Wilander is worried how much more of a beating his body can take:
“We are getting used to expecting him to not be able to play. He is always trying and is always ready. He is trying but he just can’t do it and I guess with every year it seems like he’s playing less and less. He is getting older and his body is taking a beating.”
