The Barcelona star had taken a bet with the coach, saying that he would score against the Mexicans, but the tactician won...
Messi is still without a goal in the tournament, and came close this evening to chipping the goalkeeper, but team-mate Carlos Tevez got the final touch on the ball.
"I could have scored a goal this evening," Messi told Ole post-match. "I had many shots, but had no luck.
"Hopefully, I will get one against Germany.
"We played against a great team, and we were fortunate to score two goals in the first half, and control the match from there.
"We became a stronger team when we had the ball.
"I am feeling fine, and there still a few games to go. I feel comfortable and happy on the pitch.
Messi also looked towards Argentina's next match against Germany.
"Everybody knows everybody, having played one another in a friendly recently. It will be tough," he concluded.
