At his official unveiling on Tuesday, Guedes said: "I did not expect so many people or such a warm reception, I am very happy and eager to train and play, I have had difficult days because I wanted to return to Valencia, but it was complicated.
"I always said that I wanted to stay here and we did everything to return. Valencia has signed very well and we have everything to make a great season, it is clear that this year is important because it is the Centernario, but we always want to improve.
"I want to stay in Valencia for a long time and I thank the fans.
"I would like to thank Peter Lim and the management of Valencia for all the effort they have made to buy me and I want to give my best and prove that I am worth the price that has cost me."
