The versatile defender moved to Elland Road from Ipswich for an undisclosed fee last week and could make his debut in the opening game of the season against Derby.
Bruce also revealed that his team-mates are thinking positively about the upcoming season and are not even contemplating a relegation scrap.
"The players seem very optimistic," he said. "I'm hearing plenty of confident noises in the dressing room and a lot of anticipation. It's good to see with the season so close.
"We're right to feel confident at this stage of the summer. You have to be. I can't predict how soon that might happen but I'm not going into this season assuming that mid-table is our limit.
"If you asked someone to pick the three clubs who are going to get promoted, they would struggle to put their finger on them."
