Arsenal want £12 million to sell Lucas Perez.
Perez joined Arsenal last summer for £17m from Deportivo La Coruna.
But the Spanish forward was unable to force his way into the team due to competition for places and injury.
The 28-year-old's agent Rodrigo Fernandez Lovelle revealed the forward wants to leave in the summer.
Lovelle told PA Sport: "The idea is to be able to play for another club.
"We want to leave and Arsenal already know.
"Do you know anyone who is happy but has no opportunities?"
