Scottish champions Celtic reportedly value their French forward Moussa Dembele at £40m following an impressive start to the season for the 20-year-old.
Dembele, who joined Celtic on a free transfer from Fulham in the summer, has scored 15 goals in 22 appearances for his Scottish club this term, including four times in the Champions League.
Barcelona, Real Madrid and Bayern Munich have all been credited with an interest and according to The Express, Premier League trio Manchester United, Chelsea and Manchester City are also very much in the hunt.
The report, however, claims that Celtic would not be prepared to entertain offers of less than £40m for a player that scored 15 times in the Championship for Fulham last season.
Earlier this month, Celtic majority shareholder Dermot Desmond revealed that he was 'hopeful' of keeping in-demand Dembele at the club amid the growing interest.
