What a tired, faulty comparison.
When has Wozniacki beaten Clijsters or Serena? Murray has a winning record against Federer.
Exactly. Wozniacki has one major final and one semi final to her name, whereas Murray has three finals and five semi finals. Murray has wins over every one of the top players in the game, Wozniacki has never beaten Venus, never beaten Serena, never beaten Clijsters and never beaten Henin.
