The owning club can do what they want. They can recall or sell him if they think it is in their interest. Typically a season long loan for a young player will run the course and a club like Liverpool won't need to recall him because of an injury crisis as they have so many others to choose from. If they were offered good money for him however and wanted to cash in then we would lose him.
If we're paying a fee for his services, they cannot recall him. I don't know whether or not they are.
They won't recall him and they won't sell him anyway.
