Howe has paid a fee for just one player this summer – Coventry City striker Callum Wilson.
Junior Stanislas and Dan Gosling have been picked up as free agents, while money has been generated from the sale of Lewis Grabban to Norwich City.
Howe may not have been the busiest of bosses during the transfer window, and remains in the market for quality additions, but he claims to have full confidence in those already at his disposal.
He told the Daily Echo: “I have said we are looking to improve certain aspects of our squad but it is very difficult with the quality of players we have.
“I think people could see from the two teams we picked against Swansea and Oxford that we are strong.
“I would be happy to start the season with the squad we have. It is near enough the same as the one we had which performed so well at the end of last season.
“We have lost Lewis Grabban and Andrew Surman but have added three players in return so I think the squad looks in good shape.”
Asked whether he could bolster his squad ahead of a season opener against Huddersfield Town on Saturday, Howe added: “I wouldn’t rule out anything but I wouldn’t be in a position now to say yes for definite.
“The deals we are looking at aren’t really in our hands so I would probably go more negatively than positively on that one but we will have to see.”
