Mexico edged out Senegal 1-0 in the 2017 FIFA Under-20 World Cup last 16 match at the Incheon Stadium in Incheon, South Korea on Thursday.
The victory sees the Young Tricolor advance to the quarter-finals, while the Young Lions of Teranga bow out of the global competition.
The Young Tricolor were the better side in the opening exchanges – dominating possession as they looked to penetrate the Senegalese defence.
Alioune Gueye, the Young Lions of Teranga defender, was booked just nine minutes into the match as Mexico piled pressure on the Senegalese defence.
The Young Lions of Teranga were conceding too many free-kicks in their own half and Mexico looked dangerous from the set-pieces.
Senegal goalkeeper Mouhamed Mbaye was called into action two minutes after the half-hour mark and the 19-year-old produced a good save.
The promising shot-stopper also denied Mexico forward Paolo Yrizar in the 38th minute to ensure that the first-half ended goalless.
The Young Tricolor continued their dominance in the second-half, but the Young Lions of Teranga defence which was led by Gueye looked solid.
Mbaye was also alert most of the time in the Senegal goal-posts. In the 61st minute, he was well positioned to make a save from a Mexico free-kick.
However, Senegal suffered a blow in the 72nd minute when Gueye received his second yellow card and the 18-year-old defender was sent off.
The momentum was with the Young Tricolor in the closing stages of the encounter as they looked to snatch a late winning goal.
Mexico did score in the 89th minute through Ronaldo Cisnerous Mereli, who netted from close range, and the Young Tricolor emerged 1-0 winners.
