I just read an inteview with Federer and one of the questions was "Isn't it weird to face players have your age?"
But having a look at his recent matches most of his opponents were 30plus!
In Halle he beat Youzhny (30) in the semis and lost to Haas (34) in the final.
And now he beat Benneteau (30) two days ago in Wimbledon R3 and now plays Malisse (30).
Next up is probably Yozuhny again...
