Alaves have been busy this week after swooping for West Ham striker Lucas Perez.
Alaves have coughed up €2.3m to land Lucas for the coming season.
And soon to follow the former Deportivo La Coruna star will be Javi Eraso, who will arrive on a free transfer from Leganes.
Alaves coach Asier Garitano is seeking as many as ten new additions this summer.
