Mikel Arteta is enthused by what he has seen from teenager Max Dowman, as the Arsenal youngster made Champions League history.

With Arsenal leading Slavia Prague 3-0 in the Czech capital on Tuesday, Dowman replaced Leandro Trossard in the 72nd minute.

Trossard had teed up the first of Mikel Merino's goals, with the Spain international - filling in up front with Viktor Gyokeres out injured - scoring twice in the second half.

Merino's double came after Bukayo Saka's 32nd-minute penalty had put Arsenal ahead, with Slavia Prague denied a late spot-kick of their own after a VAR review.

Aged 15 years and 308 days, Dowman became the first player to ever play in the Champions League before turning 16.

Dowman had six touches and attempted three dribbles, completing one of them, during his time on the pitch.

"What he's done on the pitch, you cannot teach that, you see it on the pitch," Arteta said of Dowman.

"It doesn't matter what his passport says [in terms of his age], he has delivered."

Arteta also reserved praise for Merino, who once again stepped up when deputising as a centre-forward.

"We are lacking a lot of attacking players and he had to step up," said Arteta.

"You have to invent options. Obviously, Mikel hasn't played there before in his career, but from the way he reacted in that position, it was a good chance for him to perform."

Arsenal have won their last eight matches without conceding in all competitions, the joint-longest run ever by an English top-flight side, matching Preston North End (between January-September 1889) and Liverpool (between January-February 1920).

"If we are able to nullify their attack, then the opposition has very few ways to score," Arteta added.

"We could have done some things better. But we did things really well too."
