The world of football was in mourning on Thursday after Barcelona and Netherlands legend Johan Cruyff died at the age of 68.
A three-time Ballon d'Or winner, Cruyff is widely regarded as one of the greatest players of all time and also one of the most influential managers following spells with Barcelona, Ajax and the Netherlands.
He has been praised for revolutionising Barca and called the greatest player of all time. Here's what else was said about him...
"All the coaches I had in my career were important but Cruyff was the most important of all. He was without equal on training and tactics and he helped me to understand the million details that decide why some matches are lost and some matches are won." - Pep Guardiola, who played under Cruyff at Barcelona.
"There were matches when he did with a ball what no one else would dare to try. Was he the greatest European player of all time? On form, it's difficult to imagine who was better. It does not matter how and where you remember Johan playing, he was the best; in midfield he was the best; deep, the best; as an attacker, the best." - Former Barcelona head coach Terry Venables.
"Johan is so technically perfect that even as a boy he stopped being interested in that aspect of the game. That's why he's been very interested in tactics since he was young. He sees football situations so clearly that he was always the one to decide how the game would be played." - Former Dutch team-mate Marco van Basten.
"As a player he turned football into an art form. Johan came along and revolutionised everything. The modern-day Barca started with him, he is the expression of our identity, he brought us a style of football we love." - Former Barcelona president Joan Laporta.
"I loved the Dutch in the '70s, they excited me and Cruyff was the best. He was at the heart of a revolution with his football. Ajax changed football and he was the leader of it all. If he wanted he could be the best player in any position on the pitch." - Former France international Eric Cantona.
"Johan Cruyff painted the chapel, and Barcelona coaches since merely restore or improve it" - Guardiola.
"His years as a player at the Nou Camp changed Spanish football and Barcelonismo. He single-handedly introduced a new way of playing football in Spain. It was a revolution." - Former Barcelona player Eusebio.
"Without him, the Xavis, Iniestas and Thiagos of this world wouldn't exist." - Journalist Oriol Domenech, who was in Barca's youth teams during Cruyff's era.
"Cruyff reinvented the concept of football in this country. Today, Barcelona and Spain are the ultimate modern testimonies to his spell as coach." - Former Barca defender Miguel Angel Nadal.
"Johan Cruyff is, pound for pound, the most important man in the history of football. If he had not installed a culture, a philosophy at the Nou Camp, then Lionel Messi would have been rejected and sent home as an underdeveloped 13-year-old kid. Andres Iniesta wouldn't have been selected." - Journalist Graham Hunter.
"He laid the foundations for what you see now (at Barcelona). He was responsible for the major turnaround of the club, for stopping the domination of Real Madrid. In the two years before I joined Barca and before it really got going, Cruyff had a massive clear-out. It was like a revolution." - Ronald Koeman.
"Cruyff thinks he's always right. The funny thing is, he really is always right." - Ex-Ajax striker Johnny Bosman.
"A real football brain. He had superb control, he was inventive and he could perform magic with a ball to get himself out of trouble instinctively. He got a lot of goals, and although he was so skilful, he didn't show off - he played to the strengths of the players around him." - England World Cup winner Bobby Charlton.
"For me he is the best of all time." - Former France international Michel Platini.
Cruyff on his footballing philosophy
"Football is simple. But nothing is more difficult than playing simple football."
"In my teams, the goalie is the first attacker, and the striker the first defender."
"If you play in possession, you don't have to defend, because there's only one ball."
"You have got to shoot, or you can't score."
"If you want to play quicker you can start running faster, but it's the ball that decides the speed of the game."
