On-loan from PSG this season, Guedes is attracting interest from beyond Los Che.
Marcelino said: "We all agree, we would all be happy that Guedes stays with us a long time.
"Peter Lim (VCF owner) helped us to bring him in, and I think he will try it (to keep him). Footballistically speaking, there is no doubt about Guedes.
"After there is the market ... any average English club has more financial power than 17 clubs in LaLiga."
