Show posts from other sites on my WP site

I have this perfect domain for betting tips in Swedish and i first had some plans to post my own betting tips each day but this will take allot of time that i have to put in other projects and i come over this other idea i seen on some other sites.

I guess most betting site have a rss feed from where i can catch there new betting tips each day, i do not want to copy the text and add to my site but just the post title and two - three rows from the beginning of the text. When someone clicks the post they shall come to the website were the betting tips is posted.

It would be good if they stayed on my website but the other website were the betting tips are shows in a external window.

Here are one example:
http://bettips.se/

Are there any plugins or anything for this?

 

Have a look at WPeMatico: https://wordpress.org/plugins/wpematico/

 

Have you tried using the RSS widget if you're planning on adding it to your sidebar

 

There's heaps of RSS plugins that will do this. Problem is the feeds won't just have tips but other posts from the site.

 

You could just get the specific category
