Porto president Jorge Nuno Pinto da Costa insists there's been no offers for Eliaquim Mangala nor Jackson Martinez.
Manchester United, Manchester City and Chelsea have been linked with the pair.
"Every day there are stories that one club or another wants Mangala but Porto have not received a single offer for him," the Porto chief told EFE.
"It is the same with Jackson. His name has been in every paper but nobody has contacted us about him."
