LORNA JOHNSTONE of Troon asked Derek what was the toughest away ground he played at?
Games against Dundee United at Tannadice and Celtic at Parkhead were always hard.
But Pittodrie was a very difficult place to go. I only won twice against Aberdeen away in my Rangers career.
Jim Leighton, Willie Miller and Alex McLeish made the Dons tough to beat.
