Barry Robson insists there is much more to come from Aberdeen despite a bruising defeat against Celtic.
The interim Pittodrie boss admitted his squad are still fragile after Jim Goodwin's departure but is confident he can help transform the fortunes for the club.
A heavy defeat in Glasgow was a body blow for confidence at Aberdeen after improved performances against St Mirren and Motherwell in recent weeks.
"I'm frustrated," Robson told BBC Sportsound after the defeat at Parkhead. "I think you saw we were starting to build momentum with a group who have been really fragile.
"I knew it would be a difficult game and you lose that first goal and then all of a sudden you can see and feel that fragility coming back because it is still not totally out of their system.
"Sometimes the difficulty in football is - I've said it before - is when a team is that good against you it's hard to have a go and then when you lose a goal so early that makes it really difficult for you.
"I'd love to come down here with a team that wants to have a bit of a go and really be energetic and all the rest of it but, we've got to remember where the group are.
"I understand that and I know that but I do also know that there is so much more we can get out of them in the coming weeks."
On his experience as Aberdeen manager in an interim capacity, Robson added; "I've been built for this my whole life. The way I played, the way I am, football is my life.
"Does it scare me? No. Do I enjoy it? Crazily, yes.
"And I know I can make football players better and I've got a way of working and systems that are good and can work."
