Marcelino Nunez scores one of the coldest penalties you'll ever see, didn't even watch it go in

Marcelino Nunez scored one of the coldest penalties you'll ever see in Norwich City's penalty shootout victory over Birmingham City on Tuesday. Check it out below:

Nunez confidently converted his side's fourth spot-kick in their EFL Cup shootout and he didn't even watch it go in.

The Chilean struck an outrageous Panenka penalty, bamboozling Birmingham goalkeeper Neil Etheridge.

Etheridge dived to his right before scrambling to stop Nunez's effort from going into the back of the net, but to no avail.

Cool as you like, Nunez turned away from his penalty before the ball even went in.

Needless to say, the 22-year-old's Panenka penalty got Norwich fans talking online.

One Twitter user wrote: "THE WALK OFF!? Like knocking a guy down and walking away knowing he’s done, this guy is too filth."

A second tweeted: "Balls of steel."

A third added: "Absolute filth."

The exciting midfielder joined the Carrow Road outfit from Universidad Catolica for an undisclosed fee this summer.

He helped his team reach the next round of the EFL Cup with his stunning penalty.

Norwich boss Dean Smith spoke highly of Nunez following the player's Championship debut against Wigan Athletic last weekend.

"I thought he was probably the catalyst for the first 30 minutes, to be honest," he said.

Nunez could feature when his side resume their league campaign on Saturday against Hull City.
