Porto have not fielded any offers for star striker Hulk.
Chelsea are being linked with the Brazilian.
But no club has made a bid for Brazil international Hulk, whose contract includes a staggering €100million (£83.5m) release clause.
A Porto source told skysports.com: "We have received no formal offer for Hulk in recent days. We are used to rumours in the papers and the club is calm."
