STEPHEN GLASS reckons Scott Brown's professionalism has been the key to his longevity as he continues to set the standards at Aberdeen this season.

The 36-year-old produced another accomplished performance on Tuesday night as the Dons were unfortunate not to take all three points at home to Rangers.

Brown has made 26 appearances since making the move to Pittodrie in the summer and continues to impress in the middle of the park.

Glass said: “To be honest, I don’t want to isolate it just to Rangers. Scott’s attitude every week is first class.

“How he drives the group is brilliant. He is an unbelievable professional.

“I was talking to Allan (Russell) about him the other day. Allan, who has worked with the England team, has said he is probably the best he has seen which is incredible at 36.

“I keep telling him he is younger to keep him playing longer. He relishes those games but he relishes every week and that is why he is the professional he is.”

Aberdeen will put their Premiership ambitions to one side on Saturday as they begin their Scottish Cup campaign against Edinburgh City.

And Glass has confirmed his intentions to add to his Reds ranks between now and the close of the January transfer window.

Glass said: “We are continually trying to get stronger so we will try to do that until the end of the window. My first experience as manager was in the January window.

“I can see why people say it's a difficult window because you don’t know what you are preparing for almost anything.

"You don’t know who could knock on the door or try and come in late. We are ready for every eventuality and we are ready to strengthen if nothing goes out as well.”
