The four-time Ballon d’Or winner has been in great form so far this summer, scoring four goals in three group-stage games as well as playing a decisive role in both the Albiceleste’s second-round victory against Switzerland and the quarterfinal triumph over Belgium.
Netherlands beat Costa Rica in a penalty shootout to set up a semifinal meeting with Alejandro Sabella's side, and Martins Indi believes keeping Messi quiet throughout the game is key.
"Argentina is still a very good team," the Dutch defender told NUSport. "But Belgium also got some chances against them. I’ve watched that match.
"Every team has strong and weak points. We have to make sure that Messi doesn't get the ball."
The Feyenoord player believes that the Oranje are improving defensively, and the tournament has helped him develop.
"Look at the way we are positioned in defense,” he said, “I'm doing things differently than I used to do, and I try to read the game a lot more.
"When you play against the best players in the world, you'll only get better."
