Andrei Ratiu, a Romanian right-back for Rayo Vallecano, has attracted interest from Atlético and several other European clubs. Rayo Vallecano had turned down offers for him in the summer when his transfer value was approximately 10 million euros. Currently, his release clause is set at 25 million euros. Ratiu's outstanding performances in La Liga and for the national team have enhanced his market value. Villarreal, which holds 50% of his rights, is keeping a close watch on potential transfer developments.
