15. Mauro Icardi

There are cheaters, and there are just downright assholes. Icardi seems to fall in that latter category. Here you seem him with his former teammate Maxi Lopez and Maxi’s wife Wanda Nara. Fastforward a few years, Mauro has stolen Wanda, married her and he got a tattoo of the children of Wanda and Maxi. Dark stuff.
