Valencia made a late attempt to bring Chelsea midfielder Juan Mata back to the Mestalla this week.
Super Deportes says Los Che officials made contact with Mata's agent to explore the prospect of re-signing their former star before Monday's transfer deadline.
Flush with the funds from Roberto Soldado's sale to Tottenham, Valencia were confident of convincing Chelsea to sell, but needed Mata's go-ahead to open talks.
However, their approach produced a negative response from Mata's agents on deadline day.
