Milan sent scouts to watch Celtic striker Moussa Dembele in a 7-1 Champions League defeat to PSG, according to reports in Scotland.
The forward gave Celtic a shock lead at the Parc des Princes, but that was the only bright spot for the Hoops, as they went on to suffer a hammering.
The Scottish Sun claims that Milan had representatives in the arena and they were watching the 21-year-old striker.
His price-tag is believed to be around £20m (approximately €23m).
Dembele is a France Under-21 international with seven goals in just 10 caps at that level.
Celtic snapped him up from Fulham for free in the summer of 2016 and he has seven goals with three assists in 14 competitive appearances this season.
