Hoffenheim signed German international goalkeeper Tim Wiese and Switzerland striker Eren Derdiyok to four-year deals Thursday.

The 30-year-old Wiese will join from Werder Bremen on a free transfer, while the 23-year-old Derdiyok will join from Bayer Leverkusen for an unknown fee.

Wiese, capped six times for Germany, helped Bremen win the German Cup, finish second in the Bundesliga twice, and to second place in the UEFA Cup during his tenure from 2005-2012.

"We didn't want to pass up the opportunity to sign such an experienced, successful and ambitious professional, and we're all delighted things have worked out," Hoffenheim coach Markus Babbel said.

"Tim Wiese has managed to break into the national team; that says it all about how good he is. I have no doubt that he will be a key factor in this club achieving its goals."

Derdiyok joined Leverkusen in 2009, and has scored 25 goals in 89 Bundesliga appearances for the club. He has four goals in 36 appearances for Switzerland.

"Eren Derdiyok is a complete striker. He fits the mould perfectly regarding the type of player we want at this club," Babbel said. "I'm pleased we were able to convince him to join."
