The important thing is not to concede in the first 20 minutes when Leeds will be at most frantic. I think, if that is achieved, it will be an away win.
I seem to remember reading that Don Revie was not against letting Bremner go, but Leeds had a run of games with a depleted squad so he was kept until after them. Apparently, Bremner played so well in them that any plan to release him was shelved.
