Best friend needs to break up w bf

Okay. So I just got a phone call from my best friends mom and she ranted to me about all the shit her boyfriend has done. Basically none of her family members like him, he works for her dad and calls in all the time and disrespects her dad, didn’t even go to their family Christmas after 8 months of dating and didn’t even get her the present she wanted the most. Little to say he’s a lazy piece of shit. And he treats her like shit. Hangs up on her when they get into an argument and calls her stupid. I want to talk to her about how he’s not any good for her (only bc I want the best for her) how do I even bring this up? None of our friends or anyone like him...plus he ain’t cute and I have a better guy in mind that would fit her perfectly. Please help
