Lionel Messi played a pain-free 45 minutes in Argentina's    3-0 win against Bolivia on Tuesday, and feels ready for the knockout rounds.

"I felt good. I felt good," Messi said on Tuesday. "No pain, right now I don’t feel anything. I felt good from a fitness standpoint too, so it was good appearance."

The match itself was another comfortable win for Gerardo Martino's men, as Erik Lamela and Ezequiel Lavezzi scored goals two minutes apart in the first 15 minutes. By the time Messi entered at halftime, the victory was assured, and the second half felt, at times, more like a training session as the Argentinians passed the ball around with ease.

"I thought we handled all of our games well, we won them comfortably," Messi said. "I wasn’t able to play much, but now it’s time to forget all this and think about this like a new Copa (America)."
