The Reds take on the Cherries at 14:00 BST on Sunday, just four days before the crucial Europa League semi-final first leg against Athletic Club.
With that fixture in mind, it was expected that Amorim might rest specific players, but the Portuguese has named a very strong XI to start on the south coast.
Luke Shaw makes his first United start since February of last year, with the England international expected to step into a left-sided role in Amorim's three-man central defence.
Diogo Dalot is absent with injury, as reported on Friday, so Noussair Mazraoui and Patrick Dorgu are likely to share the duties at wing-back.
