Is Duff Still Top Class?
The 30-year-old has insisted that he wants to remain with The Magpies and help them bounce straight back up to the top flight.
However, he might find himself being offered up as bait to other clubs in an effort to reduce the costs at the North-East club.
Due to injuries, Newcastle played him at left-back in the remaining few games of the season.
Sometimes a change of position can reignite a player's career, but all it did for Duff was show that he is hard working and definitely not a defender.
He is likely to start for Ireland in their World Cup qualifier against Bulgaria on Saturday and that will give him a chance to show that he can still deliver when it matters most.
A number of clubs will surely be watching the game.
He maintains he wants to stay at Newcastle and keep playing for Ireland, but his preferences may not matter much if he can no longer convince people that he is still a top class player.
