Manchester United midfielder Ander Herrera has denied being involved in match-fixing.
Spanish judges are investigating a game between Herrera's former team Real Zaragoza and Levante in May 2011.
Herrera said in a statement: "As I stated back in 2014 when this issue was raised, I have never had and will never have anything to do with manipulating match results.
"If I am ever called to testify in a judicial hearing, I will be delighted to attend as my conscience is totally clear.
"I love football and I believe in fair play, both on and off the pitch."
Deportivo La Coruna were relegated after Real Zaragoza beat Levante 2-1 in 2011.
