Barcelona coach Ernesto Valverde says Johan Cruyff's methods continue to influence football today.
Valverde played for Cruyff at Barca.
"His influence wasn't only on changing the style of play and his importance can be seen on impacting coaches today, you recognise elements from him, playing inside, positional approach, the lines, possession and coordination etc," said Valverde.
"Having the ball means that you want to take the initiative, attack the rival and take charge.
"I remember the arrival of Johan to Barcelona because it shook things up so much, there were a lot of changes and he had an idea and a style. The first season was terrible, we were asking ourselves each day after the sessions."
