Fans have been going bonkers over the recent booking of a former WWE champion, who left AEW to make his return to the Stamford-based promotion earlier this year. People on X believe it is a downgrade, as he was doing better in All Elite Wrestling.Former United States Champion Rusev recently wrestled at several NXT live events. It was a surprising sight for fans, as the 39-year-old had been featured in a major storyline with Sheamus on Monday Night RAW for multiple weeks. Before his WWE return, The Bulgarian Brute was working with AEW. Many believed Tony Khan was never able to capitalize on his talent during his run with the Jacksonville-based promotion.Therefore, when Rusev made his WWE return on the RAW after WrestleMania 41, it felt as if this could be the breakthrough point of his career. However, his recent appearances at NXT live events have raised a lot of eyebrows. Some people on X have pointed out the irony by calling out those who previously criticized Tony Khan for ‘fumbling’ Rusev, suggesting WWE might now be doing the same.Moreover, some people shared their opinion, saying Rusev's career has been on a downward slope for the past few years, recalling how he used to ride tanks for his entrance. Also, some fans claimed that The Bulgarian Brute's potential move to NXT could be the only hope for his career.Check out fans' comments below:Edward @MonsterE138LINKFrom riding to the ring in an actual tank at wrestlemania to NXT.
