Andy Murray: Behind the scenes with world number two

Andy Murray says he is working hard with coach Ivan Lendl to control his emotions during matches.

The British number one says one of his strengths is his tactical nous, but acknowledges that losing his cool affects his ability to "work matches out".

"If you're getting angry and worrying about what's happened in the past, you cannot use one of your best assets," said the world number two.
