Messi is in unbeatable shape: Argentina coach Martino

Argentina coach Gerardo Martino on Saturday said his star striker Lionel Messi is in unbeatable shape for the Copa America.

Messi is fresh after playing a instrumental role for Barcelona in winning the treble -- La Liga, the Copa del Rey and European Champions League. The The 27-year-old is now solely focussed on Argentina and winning the Copa America.

"This year, by contrast, he has won everything. He comes here fresh from securing those three titles and he was in superlative form throughout the season. He is in unbeatable shape," Martino was quoted as saying by goal.com.

"Last year he arrived at the World Cup without winning any titles and this year he heads into the Copa America having won three and he has been key in those, playing above his usual level," he said.

Asked about Argentina's change in style since he took over from Alejandro Sabella after the World Cup, Martino added: "The footballers play a big part in that and it is their ability to execute those ideas that have helped us.

"I believe we have consolidated and reinforced those beliefs. And on top of that, we have the best player in the world."
