Another major lightweight title fight is in the books and Conor McGregor is back at it – tweeting, that is. Following Islam Makchachev ’s title-earning UFC 280 main event victory Saturday in Abu Dhabi, McGregor posted a series of tweets directed at the promotion’s newest champion. Not only was McGregor critical of Makhachev’s second-round submission performance against Charles Oliveira, he indicated he has the tools to defeat the Russian champion if the two fighters go head-to-head. The statements attracted the attention of notable figures from around the MMA world, including manager Ali Abdelaziz and former UFC welterweight Ben Asken among others.
