Valencia CF has little choice in the matter as the club has not received a serious offer for the player which would be in the region of 15 million euros and more, but they also can't extend his contract. So might as well use the player for 6 months and then see if he maybe changes his mind about extending his contract with Valencia CF or sell him for say 8 million euros or so, a much reduced price, but still get something for him before he can leave for free next year.
