The 17-year-old winger has been impressing for the first-team at the Scottish side and Sunderland and Forest will both be getting their hands on this talent.
The report claims that Sunderland see him as potential replacement for Duncan Watmore – who is set to miss the rest of the season with a knee injury. Forest meanwhile would love another talented Scottish winger on their hands – after losing Oliver Burke to RB Leipzig in the summer.

McAllister, who is also reportedly being scouted by Leicester City and Aston Villa, is a Scotland under-17 international who has made his club breakthrough in Paisley this season.
He made his debut for St Mirren in February and is now a regular feature in the first-team picture at the club.
Both Sunderland and Forest would be getting their hands on a real talent if they could secure a move for the teenager in the New Year.
