Villarreal directors will blank their Atletico Madrid counterparts this weekend.
AS says the relationship between the two boards is at an all-time low after events over the summer.
While disappointed to have lost midfielder Rodrigo Hernandez to Atletico courtesy of his buyout clause, it has been the departure of teen German Varela which infuriated the Yellow Submarine.
Villarreal are still furious over the way Atletico ferried Varela away, believing it was a hostile transfer raid.
The 16 year-old striker is a Spain U17 international.
