Celta Vigo sporting director Miguel Torrecilla has admitted that he expects Iago Aspas to move abroad in the near future.
The Spanish forward, 25, who is understood to be on the radar of Swansea City, has an £8m release clause in his current contract.
"Aspas is a remarkable player and if his performances continue the speculation will increase," said Torrecilla.
"It will be difficult for a Spanish side to get him. The £8m we want will probably not come from this country."
Aspas has scored six goals in 17 La Liga appearances this season.
