Tuanzebe signed for Villa on loan from Manchester United, to a mixed response.
The youngster was on loan at Villa Park last season after January, but he failed to make much of an impact.
Tuanzebe struggled with consistent injury problems, but Bruce believes that the United prospect will thrive what a point to prove.
And Bruce has promised that Tuanzebe will receive regular action at Villa.
"It's great to have him back because it was disappointing for him last year. We only saw little glimpses of him as he got injured twice," Bruce said.
"It's unfinished business as far as he's concerned.
"He'll fit in anywhere across the back four – right-back, left-back, centre-back, middle of the pitch if we needed.
"He's delighted to be back and we're delighted to have him.
"The one thing he wants to do is play and get used to playing week in, week out, competitive football. He will do that here."
Tuanzebe’s versatility is one of his main assets, and it is unclear where Bruce plans on using him yet.
Tuanzebe could be used right along the backline or even in midfield, if needed.
Villa won their first match of the season 3-1 against Hull City, so it seems unlikely that Tuanzebe will be brought straight into Bruce’s starting line-up against Wigan Athletic this weekend.
