The forward joined Los Che on loan this season from Russian side Rubin Kazan and has stated he wishes to continue next term at the Mestalla but the decision lies with the club's sporting director.
“I have the desire to continue here but we must talk about it and there are topics that we must speak with Braulio Vazquez about,” he told reporters.Valdez netted three goals in 20 appearances for Rubin but is enjoying a return to Spanish football having found himself more involved in the first team.
“On my part there is no problem. I have already given my word to stay and the rest Braulio should sort it with my representatives,” said Valdez.
The attacker is confident Valencia's indifferent start to the season will not prevent them from reaching their target of European football next term.
He added: "We are better than many teams but we have to prove it on the field and not on paper. We have to correct the mistakes of the first round and reach the Champions League."
Los Che have an option to purchase the Paraguay international when his loan spell runs out in the summer.
