Hoffenheim signs keeper Koen Casteels
Hoffenheim has signed 19-year-old goalkeeper Koen Casteels from Belgian club Genk.
The Bundesliga club said Casteels signed a four-year contract on Monday. It gave no details of the transfer deal.
Hoffenheim is going into the new season under a new coach, Holger Stanislawski. It hopes to improve on its lackluster performance last season, when it finished 11th in the 18-team Bundesliga.
