You’re a valuable part of the business, and I’m rooting for your success with AEW, despite past differences. Let’s fu*king go! - Ryan," tweeted the former WWE star.You can check the full tweet here. мoнαммαd нυѕѕαιɴ@MOHAMMA88626173Ryback213Ryback https://t.co/7Eex79VAmXRyback has also expressed interest in facing GoldbergThe Big Guy has seemingly set his sights on Goldberg ahead of his repeated hints of an in-ring return.While the 41-year-old star seems interested in a showdown with Goldberg, Dutch Mantell has harshly shot down the idea. Speaking on his Storytime podcast, the veteran said:"I don't know what he's thinking. I don't think you could fill up a 2,000-seat hall, and if you put it on pay-per-view you couldn't charge 10 dollars for it, nine dollars, and I don't think they'd get that many buys then. Nobody wants to see Goldberg and Ryback."
