Porto have confirmed that no approach has been made from any club regarding the availability of Nicolas Otamendi and Jackson Martinez, according to Sky Sports.
The pair, who have been linked with a number of sides over the last few months, are heavily tipped to move away in either the January transfer window or at the end of the season, but as of yet it seems there has been no formal offers made.
Chelsea have been linked with both men in the past, with Otamendi in particular being eyed by Jose Mourinho as a potential improvement for his back-line, which has looked faulty at times this year.
Manchester United were also said to have enquired about the possibility of Otamendi, and were rumoured to be debating including Anderson in a player-plus-cash deal for the Argentinian and teammate Eliaqium Mangala.
However Porto president Jorge Nuno Pinto da Costa has quashed speculation that bids have been lodged already.
He firstly moved to laugh off the notion that the highly-rated Mangala had been the subject of a bid, before turning his attention to the free-scoring Martinez.
"It is the same with Jackson [as it is with Mangala]. His name has been in every paper but nobody has contacted us about him," Pinto da Costa said.
"Otamendi is the other name that people always talk about and no offers have been received for him either."
