I came across this YouTube video - and all the rally's in it are top quality between Lendl and Chang. It was the early 90's at the Grand Slam Cup in Munich. http://www.youtube.com/watch?v=ajg4tkJtG6k What strikes me is a number of things: 1/ The amazing versatility of Lendl's backhand. His forehand is so celebrated...but here he demonstrates how is rock solid his backhand top spin and slice are. 2/ The speed of Chang 3/ re. The Grand Slam Cup - showing the intensity of both players it shows up the myth of that not being a 'real tournament'. I remember the tournament - all of the players put in huge efforts to win it. I personally rate it equal in achievement to the WCT finals (except maybe the early 70's WCT finals when that was a defacto major).
