Duff determined to earn new deal

The 27-year-old’s current contract expires next summer, but the midfielder is keen on staying at the club.

“I have to fight to earn a new deal and I aim to do that,” he told the Daily Record.

“There is no way I want to leave with any regrets at the end of the season wondering what might have been had I not worked harder.

“I will give everything for the team until then but ultimately it is up to the boss whether he decides to keep me or not.

“Players will be leaving and others will be staying at Pittodrie, that is the harsh reality. All I can do is focus on getting into the team regularly and when I do get my chance I have to take it.

“Unfortunately, I’ve not been involved or even stripped in the past couple of weeks which has been frustrating, I understand the manager’s reasons and I have no qualms about it.

“I accept that I was not fit enough as there was a full week when I was unable to train at all. But I did extra work every day last week and it paid off.

“I got on against Rangers and if I continue to play like I did at Ibrox I’m hoping I won’t be too far away from earning a new deal.”
