Celta Vigo president Carlos Mourino concedes they're vulnerable to losing Iago Aspas.

The striker revealed yesterday there were enquiries from Real Madrid last summer.

Mourino stated: "Secure the future of Iago Aspas and Maxi Gomez? They already are with clauses.

"We must remember that the clauses correspond to what they are paid. You can not put a very high clause if the salary does not match.

"If we were to say we put in clauses to €100m, a judge would reject them immediately."
