Ex-Arsenal pair Martin Keown and Kevin Campbell hailed the goalscoring performance of Marquinhos for their Europa League win at FC Zurich.
The summer signing scored one and created the other in the 2-1 win.
Keown said afterwards, "The first of many, hopefully. He's got a huge future ahead of him. That's a real opportunity now ahead of him.
“Bukayo Saka is only a couple of years older himself, but such is the quality he's going to get chances. He looked a bit like a Gnabry type player. He's short, stocky, explosive pace. He looked very classy.
“He picked and chose his moments cleverly, whipped a couple of crosses in. Really good quality. He kept on producing.
“I think it's great news. We've seen Saka, we've seen Smith Rowe in this very competition start their careers. I think we're seeing another star here in the making."
Campbell also remarked: "For a 19-year-old, what a superb finish. Shows his emotion as well, his first goal for the Arsenal and what an absolutely great goal."
