Djokovic can not carry on the end of Wimbledon champion

Tomas Berdych of Czech Republic reached his first Grand Slam final by beating Serbian ace Novak Djokovic in straight sets at the Wimbledon Championships. Berdych, ousting the six-time Wimbledon champion Roger Federer in the quarterfinals on Wednesday, believed that he was mentally and physically stronger at the moment. Berdych is going to face world number one Rafael Nadal. I don't know what's wrong with Djokovic or Murray. Every time it is possible for them to win, however they can not carry on the end of match. Who will be the winner?
