The 22-year-old will be available on a free transfer after refusing to sign a new contract at Dutch side Feyenoord.
De Guzman has been linked with Valencia, Espanyol, PSV, Hamburg and CSKA Moscow.
His agent Jan de Visser told Algemeen Dagblad: “It was a good meeting, nothing has been signed but also nothing has been refused.
“We won’t say anything more about the negotiations or interest from other clubs.”
