When I started to do quite well on the tour I thought I'd treat myself to a bright red Ferrari. I had always had a soft spot for them as a car brand and, when I was in the position to afford one, I decided to go for it.

People think I am unemotional because my voice is flat and a bit boring. It is unfortunate but it is just the way it is. I've tried to change it but it doesn't seem to make a difference. The truth is, I have lots of emotions inside. I cried after the semi-final at Wimbledon [2012] because I was proud to reach the final and I knew how much it meant to the country. I cried after the [losing] final [to Federer], too, for different reasons. I felt I had let people down. I think people warmed to that. They could see how much it hurt.

Prayer is reaching out after the unseen; fasting is letting go of all that is seen and temporal. Fasting helps express, deepen, confirm the resolution that we are ready to sacrifice anything, even ourselves to attain what we seek for the kingdom of God.

I used to think that losing made you more hungry and determined but after my success at the Olympics and the U.S. Open I realise that winning is the biggest motivation.

To be honest, I think bananas are a pathetic fruit.

I am still been pumped to train and get myself ready for the biggest events.

I like to think I have a good few years left of my career yet, as long as I stay fit and healthy. However, it's always good to have a backup plan, which is why I have been working hard to build my business portfolio outside tennis.
