The Clarets’ Development Squad heads north of the border on Sunday for an attractive friendly against Rangers at Ibrox Park.
Burnley finished their first season in the U23 Professional Development League in impressive style, winning four of their last seven games.
And after beating Stoke City 1-0 in a training-ground game earlier this week – Dwight McNeil getting the late goal – Duff’s youngsters will continue their learning curve against Rangers’ Development side.
U23s boss Duff said: “Even though we have finished our league programme the lads are still in training so it’s good to have games to work to.
“And this is a really good one to be involved in.
“Ibrox is a great stadium to go and play in and I know they often get a lot to watch, which will make it a valuable experience for the boys.
“It also gives us a chance to continue our planning for next season.
“It will be largely the squad we have next year that will go up there and we might look at a different shape to our play as we build for next season.”
Rangers were given a year’s sabbatical from the Scottish Premiership’s Development League this season to develop their own games’ programme.
The Gers’ Academy, whose manager is former Dundee United midfielder Billy Kirkwood, have played games against top clubs from the Premier League and Europe and after the game against Burnley will take place in the Volksbank Cup in Germany next week.
Sunday’s game at Ibrox kicks off at 2pm with admission £5 for adults and £2 for children.
