Inter had claimed to be in "advanced talks" over a move for the Chile international midfielder but the Welsh club maintain they will not sell their man for a loss
Inter director Piero Ausilio claimed on Thursday that talks over the Chile international were in an "advanced state".
Reports also suggest that Galatasaray are keen on a move for Medel, who joined Cardiff in an €14 million deal from Sevilla last August.
"We are not going to take a loss on a player who was a World Cup star in Brazil," Dalman told WalesOnline.
"We have made it clear what our price is and that won't change. We will do the right thing for Cardiff City and the player.
"Our position has not changed. There are clubs interested in him but we have not reached agreement with anybody so far."
The 26-year-old still has three years left to run on a four-year deal that expires in June 2017.
