The Fashion house has been looking for a new creative director following the sacking of John Galliano and the CHANEL designer thinks the Givenchy boss would be the perfect replacement at the French label.
He told W magazine: "Well I'm not a consultant there, but I think Riccardo Tisci would be good, and then Haider Ackermann at Givenchy - not because they're friends of mine, but because they're good."
Although Haider has been tipped to take over from Karl at Chanel, he dismissed the speculation saying: "It's not his world I don't think."
Meanwhile, Karl also revealed how he thinks suits by Tom Ford don't look good on him and think they look better on his younger friends.
He explained: "Tom Ford is not as good on me as younger men. And you know why? Because I wore the same kind of clothes thirty years ago-Italian-made by Caraceni. I love the way Tom Ford suits are made. They're chic; they're elegant. But on my younger entourage, they look better than on me.
"I wear Dior Homme - my old Hedi Slimane suits. The ones they do today, too, as long as they don't get too flou. And a little Lanvin. I used to love Margiela, but it's not him anymore and it shows a little.
"You know, I hate made-by-order clothes. It's up to me to fit into them, not to buy some orthopedic stuff to get the body into. I never had one button touched on a Dior suit. Size 48 is my perfect size."
