The Magpies have not made a signing this summer but Bruce is hoping to tie up a deal for Joelinton.
When asked about transfers Bruce said: “Of course we have, but the whole club is geared up to do that in the next few weeks.
“You don't have to be a rocket scientist to see where we are light and we are going to spend the next three weeks working on it.
“We're going to need at least three or four in."
When asked about Joelinton specifically, Bruce said: “I'm not sure we are with that, I've not spoken to Lee (Charnley) since I got there.
“I was in bed at 19.30 last night.
“I am aware I need to bring players or we are going to be light."
