Manuwa needs to knock it on the head. He retired for good reason. I've got many good memories of Jimi Manuwa in the UFC, all of which (mostly) involve someone being KO'd (not always him either), he was good value for money was Jimi. But my strongest, weirdest memory is him cageside in a jogging suit at some huge PPV card talkin trash back and forth with a laughing/almost disbelieving DC:
"One punch. Just one punch. One punch"
