The 22-year-old shot-stopper gained some valuable knowledge when he linked up with the Bundesliga club for a week ahead of the 2014/2015 Premier Soccer League season.
"I got a taste in pre-season [of what it feels like to play abroad] when I went to Hanover 96, it makes you think again. Players in South Africa think everything here is the best, when you go there you can see how motivated the players are for training," said Williams.
"They go in an hour, two hours before training, here we get to training 30 minutes before. There [Germany] they love the game and I want to go there. I think I have the talent to go there and hopefully in time I can get there."
Williams added that he has no intention on joining any of the so-called 'big three' [Kaizer Chiefs, Orlando Pirates, SuperSport United], and that if he had to move it would be abroad.
"I am at SuperSport now, why would I want to join one of the big three. SuperSport is one of the big clubs here and now with a coach like Gordon [Igesund] who wants to win everything, why would I want to go there," Williams added.
"I would like to play in any league oversees, I think I have the capabilities to play in any of those [European] leagues, but the Bundesliga is on another level."
