Read the comments to this tweet. I don’t get the bitterness when it comes to Federer. A bitterness that you don’t see with Nadal and Djokovic. What has he done to deserve it? One commenter did bring up a good point. Nadal and Djokovic are 5+ years younger than Fed. Who has even come close to challenging them they way they challenged Fed? The fact that Fed has 20 slams and most likely one or both of them will pass him shows how weak their era really is.
