Unseen footage emerges of Lionel Messi's reaction to Emi Martinez's world-class save against Randal Kolo Muani

Lionel Messi’s reaction to Emi Martinez’s world-class save against Randal Kolo Muani in Argentina’s thrilling World Cup final win over France has surfaced online.

France boss Didier Deschamps made a huge tactical switch in the first half after taking off Olivier Giroud and Ousmane Dembele for Marcus Thurman and Muani respectively.

Messi restored Argentina’s lead early in the second half of extra-time before PSG teammate Mbappe completed his stunning hat-trick from the spot-kick.

Footage has since emerged on social media of Messi showing a laser-like focus and not celebrating Martinez’s huge save against Muani.

Fans hailed the 35-year-old Argentina captain’s reaction, which almost paid off for Messi as he helped launch his side’s immediate counterattack against France.

“Messi’s whole international career flashed before his eyes,” one fan said in response to the footage.

Another simply tweeted: “Ice cold.”

“Literal nerves of steel,” a third Twitter user posted.

Someone else commented: “He saw the miss and he was like, ‘Yeah, there’s no way I’m losing this.’”

A fifth fan added: “He knew he was going to save it.”

A crestfallen Muani admitted that his chance to steal a late France winner against Argentina will be a moment he will never forget.

“I still watch it, I know it off by heart,” he told beIN SPORTS.

“In my head, I said to myself -- Randal, you have to shoot now. I tried to shoot towards the near post but the goalkeeper made a very good save. But there were other options.

“I could have lobbed him, or find Kylian Mbappe [who was free on the left]. But in the moment, I didn’t see him. It’s only when you watch back that you discover the other options.

“It’s too late. It still sticks in my throat and it’ll be there for life.”
