Arsene Wenger thinks the personality of Nottingham Forest favourite Brian Clough is permanently stamped on the English game.
Clough was in charge at Forest for 18 years until 1993 and the two met after a match once he had retired.
“We didn’t speak a lot after the game because he was already fatigued,” the Gunners boss said.
“He was very lean and you could see he was no longer at full power. But of course I had huge respect for him.
“When I was young I looked at the big managers who were successful. For me then, Brian Clough was a guy on another planet.
“Today everything is available, but at the time you had to look for information. I used to travel in my car at night to watch managers work and watch their training and then come back home in the next morning.”
