Is it the end of federer??

Is the end nearing for once king of the court champion roger federed as he is being eclipsed by the giant nadal who recently won the french open,the wimbeldon and the olympic gold medal.They has always been a cutthroat competition between nadal and fedrer with one being better than other on certain type of pitches they are playing on like nadal favours clay based pitches but that scenario has changed recently with nadal playing a lot better on all type of pitches clay and grass alike where as the performance of the federed taking a hit as he has not been performing well recenelt.but this doesnt necessarily mean he is out of the picture still he is one of the greatest tennis players ever and as they say "form is temporary where as class if permanent and can never be out done".So all the federer fans are hoping for better times and is defnitely not the end of his era
