Remain totally unconvinced about Kneedal. His purported knee problems have been going on for years. They are not simply the matter of a damaged tendon that can be treated and Tsonga can return to action. Didn't you say Tsonga retired from that match injured? Nadal fought on to the last game of that 5 setter against Rosol. He showed no indication of knee problems during that match. The knees were only given an airing by way of an excuse after the match. During his absence wasn't Kneedal playing golf, which is another sport hard on the knees? Since returning has Kneedal given any indication of joint protection techniques? I think you yourself drew attention to those photographs of him sitting back on his knees after his first win? No whatever the reason he was out for 7 months, you can very sure his knees had nothing to do with it, (in my opinion).
