Valencia coach Ruben Baraja says Peter Federico is available for their clash with Almeria.
The winger has arrived from Real Madrid this week.
Baraja said: A situation arose to reinforce the wing, where we didn't have too much, and he is a footballer with those characteristics.
"He comes here with the desire and ambition to do things well. He is going to integrate into the group quickly and we will prepare him as best as possible so that he is available as soon as possible.
"He will be in the squad tomorrow."
