#4. Jimmy Manuwa - former UFC light heavyweight
Jimmy Manuwa is another UK fighter who began his UFC career in incredibly impressive fashion. He joined the promotion with a perfect 11-0 record and then finished his first three opponents to earn his main event opportunity. He would finish his career with the promotion with two main events to his name.
The first of his two headline bouts came against Alexander Gustafsson at the O2 arena, putting his undefeated record on the line. He suffered his first defeat on that night but went on to earn another main event opportunity at the same venue, this time against Corey Anderson.

Manuwa won that bout via first-round KO, which earned him a title eliminator fight next time out. While he ultimately never fought for the gold, Manuwa played a big part in putting UK MMA on the map and was an incredibly dangerous striker at his best.
#3. Leon Edwards - UFC welterweight
Leon Edwards was not a fighter who set the world on fire when he first entered the octagon. He lost in his promotional debut but has improved vastly in recent years and eventually earned his first main event in what was his 10th fight for the company.
That main event came against the legend Donald 'Cowboy' Cerrone and saw Edwards win via unanimous decision. His next main event saw him defeat a former champion in Rafael dos Anjos whilst his most recent headline bout was a no contest against Belal Muhammad.
Despite that one recent blip, Edwards is now unbeaten in his last 10 bouts and has now earned a welterweight title shot against champion Kamaru Usman. That fight will be his fourth main event for the promotion and while he will likely have more beyond that, should he win, he could become a huge star in the sport.
