Liverpool boss Jurgen Klopp is expected to seek an attacking midfield signing this summer.
The Liverpool Echo says Klopp has plans to be busy in the coming months.
Cantwell has starred for Norwich this season, netting six goals from midfield, though the Canaries are in desperate trouble.
Ake has consistently impressed for Bournemouth though has spent a large part of this season injured with Eddie Howe's men struggling.
And Doucoure would fit Klopp's midfield dream with the Watford star expected to leave Vicarage Road should the Hornets drop into the Championship.
