It has been reported that Valencia are refusing to do business with interested clubs over the sale of Nicolas Otamendi.
A raft of major European clubs are eyeing the Argentine defender, with Manchester United heading the queue.
However, thus far, Valencia have referred all enquiries to Otamendi’s €50 million buyout clause.
The centre-half is tied to the Mestalla until 2019.
Otamendi, 27, moved to Valencia last year from Porto.
