Valladolid began the day by snapping up 18 year-old left-back Adam Aznou from Bayern Munich.
Aznou returns to Spain after spending three years inside Barcelona's La Masia youth system. The teen joins on-loan to the end of the season.
Valladolid have also signed Hoffenheim midfielder Florian Grillitsch. Like Aznou, Grillitsch joins Valladolid in a straight loan to the end of the season.
And Valladolid welcomed Antonio Candela from Serie A Venezia.
The wing-back arrives on a deal to the end of the season. This term, Candela made 14 appearances for Venezia.
