Boxing, mixed martial arts and tennis are the hardest sports to train for.

I am not stroppy at all.

Having a normal knee would make life a lot easier.

I didn't practise it loads when I was at the academy in Spain, but when I got on the ATP Tour it's something I dedicated a lot of time to.

Many Christians backslide...They are unable to stand against the temptations of the world, or of their old nature. They strive to do their best to fight against sin, and to serve God, but they have no strength. They have never really grasped the secret: The Lord Jesus will every day from heaven continue His work in me. But on one condition-the soul must give Him time each day to impart His love and his grace. Time alone with the Lord Jesus each day is the indispensable condition of growth and power.

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.

Like most guys, I've always liked watches. I can always check the time on my phone, but having a watch is so much better.
