Andre Gomes has secured a permanent deal at Valencia after spending the 2014-15 season on loan from Benfica.
The 21-year-old, who scored four goals in 37 appearances for the Spanish side, is believed to have attracted interest from Manchester United and Chelsea over the course of the campaign.
However, the midfielder has opted to remain at the Mestalla by signing a five-year contract.
"I am very happy to belong completely to the Valencia CF family," Gomes told the club's official website. "I have always been calm about things because what I wanted was to continue here and it is what the club wanted as well.
"I can only thank the fans and my teammates for making me so happy. Now I hope to repay the confidence placed in me by playing good football and achieving good results."
Gomes spent two years in Benfica's senior team.
