Sevilla sports chief Joaquin Caparros has confirmed they plan to buy AC Milan striker Andre Silva.
The Portugal international has been a revelation since his summer loan arrival.
Caparros said, "We have all the rights, the preferred option to stay is with him, he can see what Milan wants, other teams will want him, we are aware that at the end of the season or before we will use that right.
"A contract of several seasons, Sevillismo has to be calm because he is a player that we have secured well."
Sevilla's transfer option is set at €38m.
