Reports are today linking Celtic and Sporting Lisbon with Dundee United midfielder Stuart Armstrong.

The Scottish champions are said to be long-time admirers of Armstrong but now Sporting have emerged as potential suitors for the attacking midfielder.

Sporting, of course, recently signed Ryan Gauld from Dundee United.

The reports suggested that Sporting feel Armstrong could make an immediate impact on their first team if they swooped for him.
