Bruce was an interested viewer, as Leeds won 2-0 at Barnsley, as they are his Villa side’s next opponents.
And the experience boss is wary of the attacking threat that Leeds have.
“I watched them on the TV today and they're a good side,” Bruce said.
“They've got some good players up the top end of the pitch. We'll have to defend well.
“We're also playing well ourselves, which makes for a cracking game at Elland Road.
“It's live on the television and will no doubt be in front of a full house.”
Leeds have the likes of Samu Saiz and Gianni Alioski, who are both in sparkling form.
The attacking midfielders both scored for Leeds against Barnsley, as Thomas Christiansen’s side picked up an important victory.
Villa also won at the weekend, with Albert Adomah scoring both their goals in a 2-0 victory over Ipswich Town.
Villa have been in excellent form recently, and will pose a big test to Leeds on Friday.
Villa and Leeds are both chasing top six places this term, and three points would be a major boost for either side’s promotion chances.
