I think his focus should be on us open rather than wimbledon. I don't get why people are soooooo fixated on wimbledon. He already has the record there. 8 slams. US open on the other hand he is tied with sampras. if he wins one more us open and becomes the sole record holder for us open, and that too 10 years after he won his last one its much bigger than a 9th wimbledonFederer needs to go all in for this year Wimbledon. Realistically speaking this is his last chance for Slam I guess.He is not winning US Open I think and nobody knows in what form he will be 2019.
