3. Attitude
When it comes to mental toughness and confidence, Fed has it in abundance. He realises over the last two years that Djokovic, Nadal and recently Murray are all as good, if not better than him at the moment. Still, this doesnt stop him winning prolifically because he knows that on his day, he can still wipe the floor with all three. When you have won as consistently and as much as Federer has, it can be difficult to stay motivated, especially when some young pretenders come along and start beating you. However, Fed has never shied away from a challenge, and his winning competitiveness is as strong as ever. His Wimbledon triumph in 2012 is living proof that everything is alright with the Fed express upstairs, and expect to see an eighth title appearing this year.
