Rleated posts plugin for multisite

I have the posts on my main domain, i want a plugin which allows me to place widgets/texts of the posts from my main domain with links to the post on my sub domains, it does’nt matter how they chose the posts, i just want wone that works on multisite, preferrably if i can place it at the bottom (but widgets would do), also i want to place the links on the home page of the sub domains
