Mexico manager Gerardo "Tata" Martino said he would do "everything possible" to knock out his home country Argentina and star player Lionel Messi from the World Cup,

Argentine-born coach Martino, who was Messi's coach at Barcelona during the 2013-14 campaign, was blunt in his assessment on knocking out his former player from the tournament.

"What would you do in my place? I know where I was born, I'll tell you the year, the name of the hospital, the city's area code," Martino told a prematch news conference on Friday. "But I have to do everything possible for Mexico to win."

While Mexico are heading into Saturday's match at Lusail Stadium with a point after a 0-0 draw with Poland, Argentina will be desperate to bounce back after a shocking 2-1 loss to Saudi Arabia in their World Cup opener.
