Mexico defeated Gabon 2-0 Sunday on two goals by Giovani dos Santos, taking the lead in Group B of the Olympic soccer tournament.

Dos Santos, who plays for Tottenham, played a great match in helping Mexico notch the win.

"I think we won convincingly, we were better than them and we took the match. The team improved considerably in all aspects with respect to the game against (South) Korea. We knew it was going to be tough," coach Luis Fernando Tena said.

Mexico, touted as a favorite to bring home a medal from the 2012 Games, had to settle for a scoreless tie last Thursday in Newcastle with South Korea, a perennial nemesis for the Mexicans since the 1948 Olympics.

"Gio is a force soccer-wise and psychologically. The player is improving physically and perhaps he'll start a match soon as a star," Tena said, adding that the former Barcelona player could help Mexico "even more if he got more minutes."

Mexico has not made the Olympic quarterfinals since the 1996 Games in Atlanta.

Dos Santos scored his first goal in the 62nd minute and nailed his second goal in the 92nd minute on a penalty kick. EFE
