Ryan Gauld is on the verge of moving on loan to Celtic, according to reports.
Portuguese newspaper O Jogo claims that Gauld will be loaned to a British club, and Celtic Park is the 19-year-old's preferred destination.
The Scotland Under-21 international joined Sporting Lisbon from Dundee United last summer for a fee of £3m.
He played mainly for the reserve team last season, and Sporting Lisbon appear to be prepared to allow the youngster to gain more first-team experience.
