The only goal of the game was scored by Mexico winger Hirving Lozano in the 35th minute. Following the match, Lozano was named the best player of the game.
Commenting on the results of the match, Lozano said it was the best goal in his career.
"It's the best goal I've scored in my entire life. We all dream of playing in a World Cup — and to start in such a positive and important way — I think it's my best goal so far," Lozano said, as quoted by the FIFA website.
The winger then added that he didn't know "if it's the biggest victory in (Mexico's) history, but one of the biggest for sure. It's great to start on the right foot when you are playing the world champions."
According to Mexico head coach Juan Carlos Osorio said that his side was not the favorites to win Group F, despite their shock 1-0 victory.
"I think we played really well. Sweden will be difficult to beat. We have experience of playing against them. They knocked out Italy in qualifying for the tournament, so I would not go as far as saying that we are the absolute favorites to win the group," Osorio told reporters at the post-match press conference.
This is the first time since 1986 when Germany failed to win their opening match at the FIFA World Cup, they drew 1-1 against Uruguay then, and later went out to play the final. #WorldCup #FIFA #Football
