Rayo Vallecano defender Alejandro Galvez has reportedly reached an agreement to join Werder Bremen on a free transfer at the end of the season.
The 24-year-old, who is regarded as one of the brightest defenders in La Liga, had been widely expected to depart Rayo in the summer when his contract expires.
A number of European clubs have reportedly been monitoring proceedings, but according to Bild, the defender has agreed a three-year contract with Bremen.
Should Rayo lose their relegation battle this season, boss Paco Jemez is expected to be forced to overhaul his squad.
