Arsenal boss Arsene Wenger has admitted his admiration for Nottingham Forest icon Brian Clough.
The Gunners meet Forest today in the third round of the FA Cup.
Wenger said: “Of course, Clough was one of the managers I used to look at when I was a young manager.
“I looked at all the big managers who were successful. I spent time you would not believe going to see how managers worked, travelling in my car at night and watching the training in the morning, then going back home again.
“Today, everything is available, it's easier. You go on the internet and you have every exercise of every single club.
“But at that time you had to look and it was a rarity to see – Brian Clough was like a guy on another planet."
Wenger arrived in the Premier League in 1996, three years after Clough had retired, but the two men met after a game at the City Ground in the Arsenal boss's early years in England.
He added: “We didn't speak a lot because he was already fatigued and was lean, very lean.You could see he was not at full power anymore. I had huge respect and greeted him: 'All the best', and, 'Bye-bye'.
“Whether his achievement was bigger than his personality, I don't know, but he's a special person in English football."
