Rafael Nadal is unsure how he will wake up in the morning as the world number two cast doubt over his Indian Wells Masters blockbuster against Roger Federer due to a knee injury.
Nadal set up a 39th career meeting with old foe Federer following his 7-6 (7-2) 7-6 (7-2) quarter-final victory over Karen Khachanov on Friday.
The trainer attended to Nadal twice during the match as the 17-time grand slam champion’s knee appeared to flare up in the California desert.
Asked if he would be okay for Saturday’s showdown, Spanish star Nadal replied: “I hope.
“It is difficult for me to answer, because anything I say can be taken negatively, nobody can guarantee anything that will happen the next day because, in this world, anything is possible.
“But of course my goal and my idea is to be ready for tomorrow, I cannot guarantee how I’m going to wake up tomorrow.”
