The 19-year-old striker joined the Blades on a season-long loan from Manchester United earlier this month.
He told BBC Radio Sheffield: "If I was to be the only striker here then I wouldn't be motivated.
"Having competition makes you train harder and helps you develop."
"As a striker you need to be in a team that passes the ball and creates chances and this club has excellent midfielders," the England youth international added.
"The gaffer's style of play really suits the way I play so I'm delighted to be here. I'm hopeful that by the time the season comes I'm fit and ready to start scoring some goals."
