Hojlund, who joined for £72m two years ago, was United’s main striker last season and scored 10 goals in 52 games.
His debut campaign brought 16 goals after his move from Italian side Atalanta.
The move to drop Hojlund has been backed by United’s leadership.
Amorim has spent £200m on a completely revamped forward line, with Bryan Mbeumo and Matheus Cunha set to fill the two number 10 slots Amorim prefers.
In addition to Mount, England international Kobbie Mainoo could also play as a false nine – while Bruno Fernandes did the job successfully in the 2024 FA Cup final.
On United’s pre-season tour of the United States, Cunha filled the number nine role – although he also tended to drop deeper.
Seventeen-year-old Chido Obi featured for the first team at the end of last season, although at his stage of his development it is thought unlikely he would be regarded as a regular stater, with his involvement is more likely as a substitute.
