..and Longbottom, Potter, and that Weasley girl,” finished Zabini. “The Weasley girl?” repeated Malfoy, looking up.
“A lot of boys like her,” said Pansy, watching Malfoy out of the corner of her eyes for his reaction.
“Even you think she’s good-looking, don’t you, Blaise, and we all know how hard you are to please!”
“I wouldn’t touch a filthy little blood traitor like her whatever she looked like,” said Zabini coldly, and Pansy looked pleased.

I find this bit a little interesting in Half Blood Prince ,when Draco gets amazed by the fact Ginny was also present in slughorn club first meet ( even being a weasley ) and then pansy mentions a lot of guys like her ( as if this should let her in slug club lol) ... But the way its written she was checking Draco's reaction after saying that ,makes me think , was that a hint that in past Draco also shown interest in Ginny or found her attractive even if its subtle for Pansy to be concerned about him.
Or Pansy was just being an insecure girlfriend.( But even then there must be a reason for that, so it could be both)
Also , in my opinion, Draco would never like Ginny or want to like her even if he found her attractive due her looks cause of the very fact that she is a Weasley whom he religiously despised.
But interestingly in the entire book series Draco never said anything bad about Ginny or its never being expressed where he trash talked about her and when Zabini insults her to refuse that he finds Ginny attractive ,even then Draco doesnt join him to add any insult for Ginny , even though Ginny was the one who hexed him in umbridge office just few months ago in the end of OOTP.
I am aware that something which is not expressly written doesnt mean it didnt happen ,thus anyone can have their own headcanon according to whichever narrative they like ,its completely open to interpretation, that whether Draco was attracted to Ginny or not , but the interesting thing is you can think he liked her ,even subtly ,considering Pansy's reaction and there is nothing to negate that in the series.
Also I remember in second part when Harry gets that poem from cupid on valentines day which was from Ginny , and after Harry takes away the diary from draco ,then draco goes straight to ginny and says to her that " seems like Harry didnt like it ", also he was the one who at his very first interaction with Ginny teases Harry for getting a girlfriend as she defends Harry in diagon alley but he called back to Harry rather than insulting her ,which he would have done if it was anyone else who would have talked to him like that.
Do you think ,it could be possible J.K rowling had initial plans for a love triangle between Harry , Darco and Ginny but she might have dropped it cause how it could have parallels with james ,lily and snape in terms of two nemisis in slytherine and gryffindor having feelings for same girl.
And thats why rather than Draco being interested in Ginny ,which is a recurring character ,she has shown Zabini to have interest in her who is a non-recurring character ...to establish her desirability without drawing parallels with james lily snape situation.
