Walter is already a top 100 wrestler for me, just watch his 2017, he was the best wrestler of the best year in Europe in recent times.
He has been a great wrestler for 10 years and counting.
vs Daisuke Sekimoto 2012
vs Ilja Dragunov 2017
vs Tyler Bate 2019
Add to that his amazing tag team run with Timothy Thatcher as Ringkampf, he is one of those wrestlers who would succeed in every era.
