He is going to give me a heart attack: Arsenal boss Mikel Arteta jokingly react to Maitland-Niles penalty technique

Maitland-Niles converted his post-match spot-kick with the utmost composure.

The boss says Ains' confidence at taking penalties is the reason why he introduced him at the end of the match.

Mikel Arteta was asked to describe his feeling when Ainsley Maitland-Niles gets to the spot to take a pen.

The boss replied as quoted by Arsenal's website: "I told him in the dressing room that I'm going to have a heart attack because with his body language... Jesus Christ! He puts it in the net which is the reason why he was one of the subs."

How much do Arsenal practice penalties?

"We do practice but then at the end of the day it's down to the players and how calm they are, and whether they make the right decision on the day," the boss added. "Obviously the keepers get involved with that as well."

Ains came on in the 86th minute replacing Bukayo Saka.

While taking a post-match penalty, he made multiple small steps to the ball staring at the keeper and eventually sent the ball and Adrian into different directions.

The 23-year-old converted his pen in the same manner against Liverpool in the Community Shield shootout win.
