Women's U20 World Cup pits Mexican-American twins against each other

Football-playing twins Sabrina and Monica Flores have a lot in common: they look alike, both study medicine, have dual Mexican-American nationality and share a love of football.

But the two went head-to-head on Thursday night during a quarterfinals match of the 2016 FIFA U-20 Women's World Cup, in Papua New Guinea, with Sabrina playing for the U.S. team, and Monica for Mexico.

The U.S. beat Mexico to move on to the semifinals, and "after the whistle blew, Monica broke into tears over Mexico's loss," the daily Milenio reported on Friday.

Luckily her sister was right there to comfort her.

Sabrina "immediately went over to console her, putting aside the celebrations" by her U.S. teammates, the daily said.

The sisterly duel gripped Mexican media outlets, but it's not the first time the twins have clashed on the field.

At the 2015 CONCACAF U-20 Women's Championship, they also played on rival teams, according to FIFA.

"I'll always give my all without letting anything else bother me ... I really don't care who's on the opposite side," Monica told FIFA before Thursday's match.

"Of course I'll go over and wish her good luck, though," she said, adding, "may the best team win." Endit
