Robertson, who was plucked from the Forest reserves to become a double European Cup winner with Clough, was speaking at the launch of his autobiography called 'Super Tramp.' In an interview for this website, he explained how Clough's description of him had helped to inspire the title.
"Brian Clough used to rib me about my desert boots and the gear I wore - and how I appeared in the morning, unshaven. He called me a tramp, he said I was scruffy and unfit. But he said a lot of nice things about me as well. The reason I never got upset or reacted to his comments was simple - I knew he respected me as a player."
