However, according to Diaz’s agent, David Aranda, a move to the Estadio Mestalla was almost completed in the final hours of the window.
“It was a deal that was all but done on August 31 with Mariano joining Valencia”, as per an interview with Cadena COPE.

“The contracts were agreed between the three parties. The player was enthusiastic as he believed it was the best thing for the upcoming season.
“But something strange happened, it didn’t go through.”
Diaz is now expected to continue as a bit part player in Madrid this season with Los Blancos chief Carlo Ancelotti unlikely to include him in his first team plans in the coming months.
However, despite their frustration over missing out on a deal for Diaz, Bordalas and Valencia did secure two vital deals on the final day.
