"I didn't say we were interested in Ljajic. I simply said Ljajic has characteristics that suit Milan," said Galliani.
"He is a secondary striker, he is young, so if Robinho does leave then we'll consider several different players, including Ljajic.
"He is now a Fiorentina player, though and I'm sure they don't want to sell him."
