Our first team coach has seen at close range Duff's ability and forward agility in his new role as Ireland's assistant manager.
And he has no doubts that Duff - on target in the Republic's friendly win against Norway last month and eight times in 25 Premiership matches for Rovers - has the quality to go on and on.
"He's definitely getting better and better," Chris pointed out at Spurs Lodge this week.
"If I look at the type of player he is, he's predominantly a left-winger but he's had more of a licence to play up front for the Irish team in the last couple of years and in the World Cup, where he had a wonderful time.
"There were periods in that tournament where he showed wonderful ability on the right-hand side as well.
"But he's equally at home on the left flank where he gets the opportunity to run at players.
"We gave him more of a free role in the last Irish game where he could break from midfield or play off the front and he enjoys that type of role and challenge.
"I think in terms of his development as a player he's certainly come on over the last two or three years.
"He's a great player and certainly a threat. He can go past players left and right. There is no doubting his ability and he certainly has a bright future."
Chris Hughton reckons Blackburn's Irish star Damien Duff is getting better and better - and there's plenty more to come.
