Fans believe Islam Makhachev lives "rent free" in Conor McGregor's head after the UFC superstar took aim at his rival in a deleted tweet.
McGregor has not fought inside the octagon since last July where he broke his leg in a second consecutive defeat to Dustin Poirier. However he has had many public online battles which include deleted tweet crusades aimed at former opponent Khabib Nurmagomedov and most recently Makhachev.
Makhachev is friends with McGregor's bitter rival Nurmagomedov and is seen as the protege to the undefeated former champion, who has taken the rising star under his wing. McGregor hit out at Makhachev on social media last night with a fresh insult that has now been deleted, tweeting: "The Makhachevs" with an image of what appears to be a nipple on someone's leg with the caption: "When your parents are cousins".
