Think I saw Liew Daren beating Hans before in the French Open last year. There is a video somewhere on youtube, can recall him being... a bit clumsy?
But yes, when he's up he seems to give some players a tough time...
I don't know what's wrong with Liew Daren these days... we would think that he would find extra motivation and fire after reaching the QFs of AE and Swiss but now he's back down in the doldrums, losing tamely to Shon Wan Ho this time round.
Tommy also, astonishingly lost relatively easily to Shon Wan Ho.
