Bayer Leverkusen striker Eren Derdiyok has joined Tim Wiese in signing for Hoffenheim.
Wiese's arrival was confirmed on Wednesday night and prompted murmurs of discontent from the Hoffenheim faithful.
But coach Markus Babbel said he could not miss out on Germany's number two goalkeeper.
"We did not want to let the chance of getting such an experienced and successful goalkeeper slip away," he said on his club's website.
"Tim Wiese has made it into the national team and that pretty much says everything. I am convinced he will be a key factor in us reaching our goals."
Wiese will contend a place in the Hoffenheim goal next season with the club's vice-captain and fans' favourite Tom Starke.
Derdiyok arrives to fill the void left by the sale of Vedad Ibisevic to Stuttgart in January.
"Eren Derdiyok is a complete striker and he fits in perfectly with our concept," said Babbel.
"I am delighted we have been able to convince him to come."
The 23-year-old has scored 25 goals in 89 Bundesliga matches for Leverkusen since joining them from Basle in 2009.
