Sevilla coach Julen Lopetegui has welcomed the signing of Papu Gomez.
However, the former Atalanta captain has been warned he must meet expectations.
Lopetegui said, "We welcome him first. He is a player we like.
"But Papu is also facing the greatest challenge of his career, which is Sevilla. He comes to a team that works and comes to help us.
"Improve internal competition to improve external performance. That's what I can say about Papu as you would any other Sevilla player."
