Speaking to the media, Arteta said: "Yeah, it is special. Obviously, what he's done today against this team in the time that he had on the pitch is something certainly not common to witness for a 15-year-old. We are extremely happy to have him.
"I think again the environment that he's around in, his family, the people at the club and around the academy as well, super helpful because they put him into this position so early in his journey, having a real chance and a real presence when he plays for the first time."
