As well as enjoying a 90-minute run-out in the City's 1-1 draw with North Ferriby on Monday, Aluko scored one and set up another for Yannick Sagbo during the Tigers' 2-0 win at York two days later.
"Sone looked bright again at York," said Bruce to the Hull Daily Mail. "He's worked extremely hard all summer. He's not had much time off. He worked in a training camp that we set up for him (in Portugal) and it was vitally important both for him and Robbie Brady.
"There's no kid gloves anymore. Touch wood, he looks as good as I've seen him. I've known him a long time and he looks great at the moment.
"We just have to hope it stays that way because we all know what he's capable of."
