Despite of his age, Neuer is still by far the best goalkeeper playing on the Bundesliga. No one can be compared to him. He has the highest diving, handling, kicking and speed stats. Péter Gulácsi, our second choice, is slightly better than Roman Bürki.
If you want someone cheaper, you can try Jiří Pavlenka. He is one of the tallest and he has good reflexes and diving. Sommer, Hrádecký and Casteels are other decent choices.
