That's according to Denmark manager Kasper Hjulmand, who has included the 20-year-old in his latest squad after watching the striker train at United's Carrington base.
Have two wins from their opening three games but have largely underwhelmed so far, so will welcome the opportunity to blood their £73million summer signing against the title hopefuls at the Emirates Stadium.
“I’ve been in Manchester to watch Rasmus train and he’s in full gear, so he’ll probably be in the squad for the weekend," Hjulmand told reports.
"There is of course a caveat, and he must show that he is ready this week."
Hjulmand also confirmed that a plan has been discussed with United over Hojlund's minutes for the forecoming international break.
Denmark play San Marino and Finland in Euros qualifiers next month.
"I have been in Manchester and have some clear agreements with the club," he said. "He should preferably get some minutes so that we can see that he’s there.
"He lacks game time, that’s clear, but he’s going to play a role, so we’ll have to see what he can do."
