On Wednesday, 1. FSV Mainz 05 announced the arrival of José Rodriguez from Galatasaray SK.
The Spanish midfielder joins on a four-year deal from the Turkish giants, with the fee remaining between the two clubs. It is, however, believed to be around €2m.
Rodriguez, who earned his footballing education with Real Madrid, admitted he was "really looking forward" to linking up with his new team.
A rapid recent rise
Rodriguez joined Real back in 2009, beginning his rise through the youth teams to the under-19 side and then Real Madrid Castilla.
He struggled to break into the first team - where he made just one appearance for Los Blancos - and was largely limited to the reserves.
A loan to Deportivo La Coruna followed, allowing Rodriguez to showcase his talents on the first-team stage and earning him a move to Galatasaray.
He made 23 appearances while in Turkey, and will now hope to nail down a regular spot in Martin Schimdt's side.
Schmidt's summer spend
It's been a very busy transfer window for Mainz thus far, having already signed five players including Rodriguez.
Christian Clemens had his loan move from Schalke 04 made permanent. Jhon Cordoba did the same, with Mainz paying Granada almost €7m to bring him in.
Jonas Lössl looks set to be Loris Karius' replacement, and Gerrit Holtmann also arrived from Eintracht Braunschweig.
Of course, the bulk of these deals has been financed by the sales of Karius and Julian Baumgartlinger.
Rodriguez and Schröder have their say
"He is a very gifted player and because of his age, he has huge potential for further development," said sporting director Rouven Schröder to the club website.
He added, "José Rodriguez received an excellent education in football at Real Madrid and as a central midfielder, he has considerable technical and strategic ability."
Rodriguez himself explained, "After a very positive conversation with the manager, I was sure that I wanted to take the next steps in my development here."
The Spaniard concluded, "I am very ambitious, and I want to become a better player with Mainz. I also want to help the team to follow up on their great work from last season.”
