Bruce has already landed Bosman free signings Keiren Westwood and Sebastian Larsson, who will formally complete moves to the Stadium of Light on July 1, while a deal has been agreed for South Korea international striker Ji Dong-won.
Bruce's recruitment drive could yet extend to double figures as he attempts to replace big-money departures Darren Bent and Jordan Henderson, as well as strengthen the squad which finished in 10th place at the end of the last injury-hit campaign.
However, the manager insists the club's home-grown talent will still be given the opportunity to force their way into the long-term picture, just as Henderson and Jack Colback have done in recent seasons.
Bruce told the Sunderland Echo: "I have got a few young lads bubbling underneath who have impressed me and who have got a chance.
"A lot of them can expect to be going out on loan next season because I haven't wavered from that view - that you send your young lads out on loan and see how they stand up to it."
