Celta Vigo coach Paco Herrera admits the club are powerless to prevent Chelsea target Iago Aspas from leaving the Balaídos, should another side meet the striker's release clause.
Reports on Monday claimed Chelsea have made a bid for Apas, who has scored eight goals in 18 games in La Liga this season, as the Blues strive to sign reinforcements during the January transfer window.
The 25-year-old Spaniard, according to Sky Sports, has a release clause of €10 million written into his contract with Celta Vigo and, it would seem, Chelsea may be willing to activate it this month.
Chelsea have already taken advantage of the release clause that Demba Ba had at Newcastle, bringing him to Stamford Bridge for just £7 million, and Aspas could yet follow in similar circumstances.
Although he did not reveal Chelsea by name, Paco Herrera says there is an interested party willing to meet Celta Vigo's demands for Apas and, should they do so, their is nothing the Spanish club will be able to to do to stop the transfer.
"It seems that there is the possibility of a club emerging that are willing to pay the clause," Herrera said, as reported by Sky Sports.
"In that case, if the player wants to go, Celta will not be able to do anything."
