Andy Murray insisted he is trying to tone down the bad language on court, but said: "I'm not perfect."

The world No 3 took to Twitter after his French Open third-round canter past Nick Kyrgios on Saturday after he was criticized for his colorful outbursts.

"I try 2 be a good role model but this is one of my many failings. I'm far from perfect but I do try hard to improve my behavior," tweeted the Scot.
