Henman, who retired in 2007, said it is a great challenge for players to come on net these days when the most of the game is restricted to powerful strokes from the baseline.
"Game has changed so much. I stopped in 2007, now the surfaces are slower, the balls are heavier, so it is harder for players to come on net. The players are so athletic, they hit the ball hard, they return well that makes it even hard to come on net. It is such a challenge, game is fast but it's still good to watch," Henman told PTI in an interview.
Henman said there was a lot similarities in the tennis surfaces world over, hinting that it was a hindrance in development of players, who could play different styles.
"I am a serve and volleyer at heart, I would love to see someone coming to the net more often, so difficult to do. Also the young players are not learning the art of volleying.
"For me, if I have to make a couple of changes in the game I would make the surfaces more different, it's similar these days. There are slow-hard courts, where the ball bounces high, you make clay courts very slow, you make the hard courts, sort of medium pace, and you have faster courts, indoors, grass courts and then you will get the opportunity of watching different style," he added.
