World number one golfer Luke Donald believes that his run of success is giving him "energy" to defend his Madrid Masters title despite a hectic schedule.
The 33-year-old admits that he has had to "cram in" his schedule this year but hopes that he can retain his title in Spain this week.
"It's not easy to play both tours," Donald said. "The way my schedule has turned out this year, with the FedEx Cup and my wife expecting our second child in a few weeks, I had to cram it in a little bit. It's not easy, but I'm finding the energy to keep going.
"When you are playing well the game is a lot more fun. I'm enjoying the success I've had and being in contention.
"When you are in contention adrenaline really does drive you. Hopefully I'll be able to feed on that and carry on the good results."
The British pro is working towards becoming the first player to top both the US and European money lists in one season.
