Having already seen off Andre Agassi and Ramon Delgado in straight sets with impressive performances, a rejuvenated Henman insists he is happy with his form.
"It is much more fun at the moment. I would be the first to admit I haven't enjoyed the last couple of years on grass because I wasn't comfortable.
"But in this match and my first match against Andre Agassi it is a different story and I will just try to build on that. I feel comfortable with my style of play."

Although Henman is placed at number 76 in the world rankings - just two places above Mahut - the Briton will start as clear favourite.
A repeat of his performances in the two previous rounds would see the 31 year-old into the quarter-finals, where he could have his chance for revenge against Dimitry Tursnov. The big Russian knocked Henman out of Wimbledon last year, as well as this year's Austrlian Open and French Open.
