Valencia coach Marcelino admits Goncalo Guedes has exceeded all expectations this season.
On-loan from PSG, the Portugal striker has been a revelation and attracted interest from beyond the LaLiga.
Marcelino said, "Guedes has performed beyond expectations.
"I still have a doubt about how a young player will integrate when he arrives in LaLiga. But his characteristics adapt perfectly to Spain and Valencia. He is a very high level footballer.
"I am convinced that Valencia will do everything they can to keep him, even if it is up to PSG to decide."
