Valero spent last season on loan at Mallorca and clubs such as Sevilla have expressed their interest in signing the 25-year-old midfielder on a permanent basis.
"At the moment, I only know that they are interested in me. I hope to reach an agreement because I want to stay in Spain. If there are multiple options, I would need to sit down and analyse them, but Sevilla is a very attractive team. I know that there is a good life and the atmosphere and everything has grown, it is an interesting destination," Valero was quoted by AS as saying.
"If an agreement is reached, I would love to play for Sevilla. The team is remarkable and has very good players. They will play in the Champions League next year and have won the Copa del Rey so their resume in recent years is impressive."
