Alvarez was eager to leave City after expressing his frustration at not being as heavily involved in big matches as he would have liked.
According to The Athletic, City have identified Orri Oskarsson as a potential backup for Haaland.
The forward, who turns 20 this week, is an Iceland international with much potential. It is anticipated that he could cost just under £17million.
Oskarsson has scored 23 goals in 61 games for Copenhagen, while he has provided nine assists.
The prospect signed for Copenhagen from Grotta in 2022 and also had a loan spell at Sønderjyske.
