Some Agile systems have a project manager role, but we don’t have it in Scrum. We don’t even have a role that is really similar to the project manager. The Scrum Master is only responsible for parts of the project management activities (e.g. process management, and resolving problems), and so is the Product Owner (e.g. prioritizing, and defining the scope). Even the Development Team is responsible for some project management activities (e.g. estimating).
