 Novak Djokovic is back on the court at Wimbledon today to play Alex Demonar in the quarterfinals. Plenty of people are still focused on his tirade after the last match. He accused the fans of being disrespectful and booing him when he played against Holger Ruhn. Some people, though, were quick to point out it was more likely those fans were saying Ruhn and not booing Djokovic. Djokovic says while people can cheer whichever way they want to, he'll also react when he believes the fans step over the line.
