Ethan Nwaneri's performance delighted Mikel Arteta but did not surprise him as the 17-year-old's superb strike helped Arsenal to a 3-0 win over Preston and into the quarter-finals of the Carabao Cup.
The teenager bent in a fine first-half goal after Gabriel Jesus's first strike since January had set Arsenal on their way, with substitute Kai Havertz adding the third early in the second half.
It was another stand-out Carabao Cup performance from academy product Nwaneri, who got his first senior goals with a brace in Arsenal's 5-1 win over Bolton in the previous round.
