Greek defender Sokratis Papastathopoulos has joined Werder Bremen on a season-long loan deal.
The 23-year-old centre-half moves to Germany from Serie A outfit Genoa, who only brought him back to the club for a second spell in May.
He is, however, on the move again and the agreement to take him to Bremen includes the option for a permanent deal to be struck next summer.
Papastathopoulos met up with his new team-mates for the first time on Thursday at their pre-season training base.
On the transfer, Bremen general manager Klaus Allofs said: "He is a young player who with Genoa and Greece has already gained some experience.
"With his speed, strength and tackling he will certainly help us."
Papastathopoulos, who has also taken in spells at AEK Athens and AC Milan, added on the club's official website: "After initial discussions with Klaus Allofs and (coach) Thomas Schaaf it was immediately clear that I would accept the offer from Werder.
"Now I will try to integrate as soon as possible into the team."
