I was building a Bundesliga backline and was saving for Klostermann when I packed Hummels. I noticed pace wasn't as important so I gave him a go and he was really good! I decided to keep using him and he is still very good. Even though he isn't the fastest he is still able to defend because of his incredible defensive stats and good strength, his passing also is really good and he can either play long balls from the back or shorter passes for build-up play. He is also surprisingly able to keep up with players who aren't incredibly quick but that is fine if you pair him with a player like Upamacano and/or play a formation with at least 5 defenders(in-game I play 4-1-2-1-2). He is cheap and if you don't like him you have some high rated fodder or you can sell him for presumably a slight loss
