Speaking on AEW Unrestricted in 2022, the erstwhile Cesaro said the following:"I think that was probably the funnest three years, I think with him for about three years, because everything you saw on screen, if you saw it as being from like starting as co-workers, I was just like, alright, I guess I'll make this work, to becoming best friends. We are both from Europe, so we have similarities, but we were not best friends. We were just like coworkers, We went internationally going to all kinds of football stadiums and stuff like that. If something's authentic, it will connect with the fans, I feel, and that's the stuff that you cannot fabricate."Although both Claudio and Sheamus are in different companies right now, only time will tell if the two will share the ring ever again.
