Chile boss Claudio Borghi won't be losing any sleep figuring out a way to stop Argentina star Lionel Messi when the two teams clash on Friday.
This is because Borghi is adamant there is no secret recipe to limit the Barcelona player's influence on the game and so he is better off focusing on things he can control - his own team.
"Nobody has the recipe [to stop him]," Borghi told reporters.
"In every game, he scores goals and plays well.
"You can put a personal marker on him, play a three-man, four-man defence and you still cannot stop him."
