Lionel Messi is tough to train as a player as he is already "an artist", according to Spain coach Luis Enrique, who acknowledged that the player's manager's do not need to tutor the Barcelona star on his individual gameplay.
Messi, widely regarded as one of the finest players of both his generation and the history of the game, won a record-breaking sixth Ballon d'Or last year following another successful season in La Liga.
The Argentina captain has arguably been in the form of his career even as he looks to be approaching his relative twilight years, continuing to drive the Catalan club onwards, even amid their managerial changes this season.
