Sterling was not happy with his win over Kattar

Aljamain Sterling, former UFC lightweight champion, is not happy with his debut fight in the welterweight division, in which he won a unanimous decision on judges' scorecards over Kelvin Kattar.

"If I want to defeat a guy like Elijah, I should be able to destroy Kattar. As good as he was at defending on the ground, I felt a little sad about it. I thought, 'If I can't do certain things to him, how the hell am I going to be able to do anything to Topuria?"'" - MMAJunkie quotes Sterling as saying.

As a reminder, Sterling's fight with Kattar took place on April 14 in Las Vegas as part of the UFC 300 anniversary event.
