"Possibly I'm one of the lowest spenders, but that's normal for us in the Premier League," said Bruce.
"But I have to say I am very pleased with the business we've done. Arguably, this is the best squad I have seen. Certainly it's young, with a lot to prove.
"I read somewhere last week that of the 16 - 18 players used, we're the second youngest squad in the division. That bodes well. Always as a manager you want more - that's normal!
"With what we have spent on what we've got, I am pleased. We've got a few players through the door and I'm hopeful we can still be a force in the Premier League."
He added: "When the new guy comes in - looking at all the other investors who have come into the Premier League, like at Portsmouth, Manchester City, West Ham and what they've done - we hope it will be the case here too.
"It would be a fantastic scenario if it happens. Until that day comes, I won't know."
