Rafael Nadal is looking forward to returning to action in the first clay-court tournament of the year in Chile next week, but the Spaniard admits that his injured knee is still a source of some pain.
After missing seven months due to injury and then being forced to sit out the Australian Open due to a stomach virus, Nadal will take part in the ATP event in Vina del Mar as a wildcard.
