"Roger Federer is still lagging behind in terms of fitness" - Severin Luthi
Luthi說: Roger體能上的進度仍落後.
"In terms of fitness, Roger is still lagging behind, which is a priority,"
Luthi said. "Tennis practice sessions are very intense and good, but are not
taking place that often yet like it would be in a tournament environment."
練習時狀況應該不錯, 但是Luthi擔心在巡迴賽時不是這樣 QQ
