Ole Gunnar Solskjaer started his life as Cardiff City manager by joking that he knows what it would take to be a success at Cardiff- beating Swansea.
Now he has revealed he's more learned than maybe just a throw away comment.
No side has ever done the double over the other and Solskjaer can sense this weekend might be the time to change history.
"Let's go out and make history. Why not?" Solskjaer said.
"I know about the history of this fixture... I am aware there has never been a league double. This may be the time.
"I watched the south Wales derby on television earlier this season when Cardiff won and the return is going to be another tough match.
"There is a passion among Cardiff fans which I knew about before and has been evident since I arrived.
"We understand what this fixture means to the fans."
