The Rams boss has praised the Irish trio of Conor Sammon, Richard Keogh and Jeff Hendrick after they earned a place in Giovanni Trapattoni's provisional Ireland squad
The three players have been included in Giovanni Trapattoni's provisional 28-man squad for the forthcoming games against England, Spain, Georgia and the Faroe Islands.
And Cough, who is hopeful that they will make the final cut when the squad is shortened next week, believes that the experience of international football can improve his players.
"They've all had excellent seasons and I hope they get picked for the final squad," he told the club's official website.
"Hopefully, our players being international duty regularly is something we're going to have to get used to," he continued. "If our players are featuring on a regular basis for their respective countries, it means we have good players and they're doing well to be recognised at that level.
"We said when Richard, Conor and Jeff got their first call-ups that we hoped to see them learn and develop from the experience, and we've seen little signs in the last few months to suggest they've taken things on board.
"International football is a long way removed from life in the Championship, it's more based on possession with less shots on goal.
"That's where the lads have to adapt really and learn to change their game, which only help us and them in the long-run," added the Derby boss.
Elsewhere, Republic of Ireland international Stephen Hunt has been released by Wolves after the club was relegated from the Championship.
The 31-year-old was one of several players to have been let go at Molineux as the club face into life in League One. Republic of Ireland under-21 goalkeeper Aaron McCarey, meanwhile, was offered a one-year extension with the club.
