Borussia Monchengladbach have signed Spain international Alvaro Dominguez from Atletico Madrid.
A product of the Atletico youth system, Dominguez made more than 70 appearances for the Spanish side in the past four seasons and was part of the team who won the Europa League in 2010 and 2012.
He had seen his opportunities limited since the arrival of Diego Simeone as manager in January, but the 23-year-old was still called up to the preliminary Spanish squad for Euro 2012 and made his full international debut in May's 2-0 win over Serbia.
Monchengladbach will initially pay around €8million (£6.4m) for the player's services with potentially a further €2m (£1.6m) to come in add-ons.
"It has been very nice for me to be in this house since I was 13 years old," he told AS.
"I have felt incredible and the last few years we have been able to make Atletico a big club in Europe again. I hope it continues like this and I will continue to feel like an Atleti fan wherever I go.
"I am young, I am ambitious and I want to experience other things and other big leagues. I will always take this club in my heart and I don't have the feeling I am leaving through the back door, I have helped to win two European titles in the past three years.
"I am happy and excited, because Germany is a big opportunity for me. I leave privileged to have been a part of this club and wherever I go I will always have these people and this fanbase with me."
