Celta Vigo coach Paco Herrera is delighted with the form of Iago Aspas.

Aspas is a confirmed target for Swansea City, while he has also been watched by Arsenal.

Former Liverpool coach Herrera said: "Aspas is a great player, I know, but joining this team was a big step for him. When I search for players, first I see their quality. Second, I wonder if they will fit in this environment, the squad and the city.

"Then the salary is negotiated."
