Argentina went into the game against Le Tricolor on 26 November, knowing that a victory was vital as they lost their FIFA World Cup opener 2-1 to Saudi Arabia.
Everyone was stunned by La Albiceleste's poor performance in the first half, with many criticizing Lionel Messi's display.
However, the Argentine icon took the game by the scruff of the neck and fired home an incredible 64th-minute strike to send his side on their way to victory.
The impressive young Enzo Fernandez grabbed Argentina's second in the 87th minute, but it was yet another night when Lionel Messi made headlines.
The win was vital for Argentina as it propelled them to second place, one point behind group leaders Poland, who they face in their final group game on 30 November.
Grealish was interviewed ahead of England's clash with Wales on 29 November and was among those left mesmerized by Messi.
He told talkSPORT:
“I watch all the games to be honest. We have screens all over the place and it’s just nice to have games on all day. I watched Messi, unbelievable. He just showed what he’s about in that second half but then again so did Mbappe.”
Lionel Messi reacts to Argentina's win over Mexico
The pressure had grown on Argentina following their shocking defeat to Saudi Arabia.
It went down as one of the biggest shocks in FIFA World Cup history, and Lionel Scaloni's side were in dire need of bouncing back against Mexico.
Following their victory over the north Americans, Messi spoke of his relief at securing a win as they are now back on track in Group C.
He said (via the Guardian):
“We lived with discomfort given the defeat in the opening match [against Saudi Arabia] was something we didn’t expect.
"The days felt very long and we were eager to have the chance to turn it around. We knew it was a critical game. Luckily we had the option to win and it was a weight off our shoulders, a reason for joy and peace of mind because it is all down to us again.”
If Scaloni's men beat Poland, they will qualify as Group C winners for the last 16 of the FIFA World Cup.
