Why Kidd/Hawkins/Apoo alliance are planning to take down Shanks?


Just in latest episode of One piece (Episode 736). There was one scene which
shows that Kidd/Hawkins/Apoo alliance are planning to take down Shanks.

So my question is, Why Shanks? I mean there has to be some sort of reason
behind this. Why didn't they choose someone else. What's the main reason
behind this?

Note: I follow Anime rather than Manga
