The teenage winger has joined Wanderers on-loan from QPR.
Ainsworth said: "He's definitely an exciting prospect. He can start games, he can come on after 60 minutes and terrorise defences. He'll definitely be a good player at a top club one day.
"I know Bruno from when he was about 15 or 16 at QPR and I've always kept tabs on him.
"He's a great addition to the squad and I'm so pleased for him. He did really well."
