Armstrong has made 24 appearances for Everton and played 87 minutes against the Cherries before he was replaced by Charly Alcaraz.
Speaking after the game Toffees boss David Moyes said he understood the fans’ frustration and appeared to suggest the decision was out of his hands.
“I think you always have to consider supporters; supporters aren’t always wrong,” Moyes.
“But then there are also times where I’ve had people at clubs who are really powerful and make difficult decisions.
“Managers have to make decisions on players sometimes and they feel like huge decisions. But there are sometimes bigger decisions to be made and the club will, I’m sure, make what they think is the right one.
“If I’d say something to them (the fans), I’d say their manager’s an Evertonian.”
