Valencia coach Salvador "Voro" Gonzalez said the 2-1 La Liga win over Real Madrid on Wednesday night will give his side confidence in their battle for survival this season.
West Ham flop Simone Zaza scored a superb opener at the Estadio de Mestalla after just four minutes before Fabian Orellana added a second five minutes later.
Cristiano Ronaldo pulled a goal back before the break, but Valencia refused to be further broken down and held on for an important three points.
While the result leaves Real just a point clear of second-placed Barcelona, having played a game more, Valencia moved into relative safety, in 14th place with 26 points – 10 clear of the drop zone.
After the match, Voro told the club's official website: "The intention was to have the ball, but it is very difficult to steal the ball from Real Madrid.
"We had a very good first half, although the second was totally different.
"We earned three points and whilst they are worth the same as any others, it's true that this is a special match. The fans enjoyed it and the players put in a great effort."
He added: "These three points show the way and give us confidence, but the reality is that on Saturday we have another game – and Tuesday as well."
Up next for Valencia is a trip to the Estadio de Mendizorroza to face Deportivo Alaves on Saturday.
