I wouldn't mind a little translation please, German is my Achilles' hill when it comes to main European languages!
About Wozniacki, I don't want to be disrespectful to a person who has achieved something as big as to be Nº1 in the world (even if its importance is more relative nowadays to be considered a really dominant player), but she is nowhere near Hingis' league: Martina proved to be lacking in power against powerful players like the Williamses, Graf or Seles when you take Monica's poorer movement in her second career out of the picture (shot by shot Martina couldn't stay on par with Monica's power and rally comfortably), but she was a genius tennis players with loads of talent who could find ways to win changing rythms, pace, her movement and anticipation, volleys, etc., something Caroline is greatly defficient at and renders her powerless when her retrieving abilities, which are big, are not enough to counter the very big hitters. I remember a match against Serena who, for all her greatness and tennis stature, is not the player who can hit the whole variety of shots as other all time greats, but against her raw power Caroline kept two entire sets playing the same game, and I really focused on her backhand,for instance, to see if she even tried a change, a slice, smth, as she was useless with her regular shot, and she could do NOTHING. It's really strange these last years in female tennis, as there've been so many players in the top spots whose game really came out as poor compared to earlier years top players, and I'm not even talking about a Navratilova or Seles, but even compared to the Novotnas or Martínezes of other times.
Re Graf, I disagree with you XTN as I think her forehand was not one of the best shots in history, but THE best shot ever! Seles' backhand or Serena's serve are amazing, but Steffi's forehand is still a league higher to me. And I agree with Alfa's quote, you can see it yourself if you play tennis as your faults become quite more evident when you play someone whose pace is higher or you get tight in a match, but I think the difference is that Caroline's forehand has technical flaws but she hasn't mastered her own way to hit it, while Steffi's is not right from a conventional point of view, but her way of hitting it was completely adequate and comfortable for her and she totally mastered it, no matter if no one else could hit a forehand like that so efficiently and so powerfully.
