Jose Mourinho has been making the back pages again this week as talk links him to a reunion with Cristiano Ronaldo at Juventus.
'The Special One' has been without a club since he was dismissed by Manchester United back in December, the latest on a strong list of European super clubs that the Portuguese supremo has been in charge of.
Mourinho, 56, has sat in the home dug-out at the Bernabeu, Old Trafford, San Siro and Stamford Bridge - but nowhere took his breath away quite like his trip to the City Ground .
Speaking in the foreword of a book on Brian Clough back in 2015, the three-time Premier League winner spoke of his first trip to Nottingham and his disbelief that a club like Forest could have ever toppled the giants of world football.
"I walked all the way [around the city] and when I saw the stadium I thought: 'Are you kidding me - this club won the European Cup? Twice?'
"It was a nice stadium and a nice city, but it was a small place. It was the size of the stadium that really took me aback.
"A small stadium, a small crowd - I looked around and tried to take it in."
Mourinho has been compared to the late great Brian Clough on more the one occasion thanks to his confidence in his own ability during his early years at Porto, and his unmistakable and ruthless one-line answers during press conferences.
"A lot of people say we have similarities and there are certainly coincidences," he added.
"We all probably remember Clough's best quotes. 'I wouldn't say I am the best football manager there is,' he used to say, 'but I am in the top one.' I love that line.
"He had all that self-esteem and big self-belief. He was very confident about himself, and from what I know about him he was very comfortable with the attention.
"Maybe because Brian Clough was such a huge personality, with so much charisma, everyone remembers his quotes and the stories and a few people forget his talents.
"He didn't win two European Cups with Nottingham Forest just because of his charisma.
"History cannot delete what he and Nottingham Forest did - their results, the cups, the achievements, absolutely unbelievable achievements.
"I have huge respect for what they did. I think if Brian Clough was around today, we would get on."
