This year's Wimbledon has shown me that I need to improve my game and work very hard in the coming months, both on and off the court, but I'm looking forward to the challenge.
I did manage to enjoy the experience of coming back to defend the title, and I think I did a pretty good job in the first week. I played some good stuff. The frustrating thing for me is that the kind of form that won me Wimbledon and the US Open doesn't feel that far off.
I was hitting the ball as well over the first four rounds as at any stage last year, but I couldn't find that level on Wednesday and Grigor Dimitrov played a very solid match from start to finish.
There was nothing different in the build-up and no reason to expect that kind of performance. The timings changed a bit because we played the quarter-final pretty early compared with some of my other matches, but my routine was the same and I practised with James Ward both days.
