"We try to keep an edge elsewhere and that's what we have to do as a Scottish club. We operate at our level of the transfer market and that is Scottish club level. We signed Scott Brown for £4m and will continue to do that. However, we are investing heavily in scouting and we are the best in sports science, trying to make our players better. I think you have seen that with Aiden.
"We are not a selling club, either. Aiden has three years left and we are relaxed about the situation. There has been no contact from anyone about Aiden or anyone else."
