Barcelona and Real Madrid both reportedly sent scouts to last weekend's Old Firm derby between Celtic and Rangers, with Hoops forward Moussa Dembele the subject of their attention.
Dembele, who joined Celtic from Fulham in the summer transfer window, hit a hat-trick in his team's 5-1 win over Rangers before leading the line against Barcelona in the Champions League on Tuesday night.
A tough night for Celtic saw the Scottish champions lose 7-0, while Dembele missed a first-half penalty for the visitors after being brought down by Marc-Andre ter Stegen.
According to French Football News, both Barcelona and Real Madrid had scouts in attendance to watch the 20-year-old last weekend and the two Spanish giants will be monitoring the Frenchman's performances this season.
Dembele has scored seven times in 12 appearances for Celtic this season.
