A popular star has hinted at frustration with WWE. This week on RAW, fans saw some of the top stars in action as we head towards Saturday Night's Main Event this weekend.The Megastar was also present on the show and delivered a promo, promising to become the World Heavyweight Champion and waiting for whoever wins the Title bout between Jey Uso and CM Punk.However, later in the show, he lost clean to Bron Breakker. This booking decision raises questions over WWE's plans for him and adds to the latest series of disappointments.Last week, he was eliminated from the Battle Royal to determine CM Punk’s opponent for the vacant World Title. Eventually, Jey Uso emerged victorious in that contest. It now appears that Knight might be unhappy with his creative direction.As he walked down the ramp before his match with Breakker on Monday, Knight spotted a sign in the crowd. He then took the sign from the fan that read, "We want LA Knight, not Jey." He showed the sign to the camera and said, “Can’t argue with it.”This could be interpreted as Knight showing his intensity before his match, or as the former U.S. Champion's subtle way of expressing his frustration with WWE overlooking him.Knight hasn't won a championship since losing the U.S. Title at WrestleMania 41 to Jacob Fatu. While he has floundered in the upper mid-card and main event, the promotion has yet to pull the trigger on him despite fan support.Jey Uso's win wasn't well-received by WWE fans onlineThe Stamford-based promotion posted a YouTube video of Jey Uso winning the Battle Royal, and, safe to say, they didn't anticipate the response.After online backlash against the decision, the YouTube video of Jey's win had over 40,000 dislikes in less than a day. This doesn't bode well for the former World Heavyweight Champion.However, according to reports, these dislikes won't deter WWE's booking strategy in the coming weeks.
