Roger Federer reveals who he changed his type of character on the tennis court over the years

Roger Federer, the twenty-time Grand Slam winner, has admitted that he had a controversial behaviour on the tennis court as a teenager. However, over the years, he changed his type of character. "I was a very different type of character on the tennis court, I had quite a transformation from screaming, racket throwing, swearing, kind of brat down on the tennis court. It's very strange how I have been able to put the hammer down at one point in my career and just say, This is enough. I cannot stand watching me throwing rackets and embarrass myself in front of thousands of people in a live stadium. So I tried to change. But I am happy I did that bad behaviour because I do not have the urge today act the way I used to. I am just relaxed, totally relaxed,” said Federer with a smile. Source-TennisWorldUSA
