Barca coach Ronald Koeman has said Lionel Messi was like "a tyrant" during training at Barcelona. The Argentina star raised the bar at the Camp Nou club as he developed into one of the greatest to ever play the game before departing to join Paris Saint-Germain this year.

"Lionel Messi has obscured everything. He was so good and he won," Koeman told Voetbal International, as reported by goal.com.
