I don't know what Federer thinks, but his strategies, skills and

status changes tell people what he thinks. The utlimate goal is to be a champion. Every player has its own way to go towards it, and his route reveals what he think he can use to win. It's a simple logic. Some players are wise to adjust their strategies and improve their skills after being beaten. That's why we can see changes in Nadal and Murray. Can you see any changes in Federer? If you win matches, you probably don't have motivation to change; but if you lose and don't change. What's ahead of you?
