Former Arsenal star Kevin Campbell says Marquinhos can become an Arsenal regular if he maintains his strong early form.
Marquinhos shone in victory at Europa League opponents FC Zurich last week.
Campbell told Footy Insider: “He has far exceeded expectations already though. Let’s be honest, if he performs like he did against FC Zurich regularly he is going nowhere. I can tell you that much.
“Mikel Arteta will need him to play in the cup games and be a deputy for [Bukayo] Saka.
“We’ve seen that he can come on and be that spark of lightning. He can bring in electricity to the game.”
