Aidy Boothroyd has admitted he is powerless to stop Keiren Westwood and Aron Gunnarsson leaving Coventry.
The pair are out of contract in the summer and as a result are now free to talk to other clubs.
Both players are thought to be attracting interest, with Westwood linked with a move to Premier League side Wigan Athletic.
Sky Blues boss Boothroyd is hoping he can persuade both men to stay at the Ricoh Arena but seems resigned to the possibility of two key players leaving the club.
"Yes, they can talk to anybody they want," Boothroyd told the Coventry Telegraph.
"They don't have to tell me about it and, to be perfectly honest, I won't ask.
"They will do what they need to do and if offers come in they will have a decision to make.
"But we'll continue to talk to Westy and Aron because we want to keep them. They are both terrific players and at this point in time I think this is the best place for them to be, but what will be will be."
