Moussa Dembele is reportedly set to be the subject of interest from Liverpool in January.
Former Reds manager Brendan Rodgers beat his old club to the signing of the 20-year-old striker, who has enjoyed a blistering start at Celtic.
The £500,000 capture has struck 17 times for the Scottish champions already this season but could be in line for a belated switch to Anfield.
Glasgow Live claim that Liverpool scouts have observed Dembele on five occasions this season with a view to a £20 million transfer next month.
Jurgen Klopp would have to pay £10 million up-front to prise the French forward away from Parkhead with that figure being potentially doubled by add-on fees.
Celtic are under no pressure to sell, with Dembele turning down several Premier League clubs to sign a four-year deal.
