Jamie Carragher has said that Lionel Messi has tweaked certain aspects of his game at this year's World Cup.
The Barcelona star has scored four goals in four games for Argentina in Brazil, and the former Liverpool star believes that the four-time Ballon d'Or winner is displaying a new side to himself.
Despite the changes in his game, Carragher still insists that Messi is just as "devastating".
He said in the Daily Mail: "We are seeing the evolution of Lionel Messi in this World Cup. The new version is not as dynamic, but is equally devastating.
"He has become more of an old-fashioned playmaker, with everything coming through him. He's on the prowl, smelling danger, waiting for the opportunity to pounce and to come alive at the point of maximum impact, but conserving his energy until such an opening presents itself."
