According to Norwegian editorial Adressa, Celtic have recently sent scouts to watch Rosenborg winger Pal Andre Helland.
The Bhoys made eight signings this summer, as Logan Bailly, Saidy Janko, Dedryck Boyata, Jozo Simunovic, Tyler Blackett, Scott Allan, Ryan Christie and Nadir Ciftci all put pen-to-paper at Celtic Park.
Manager Ronny Deila has strengthened his squad as the Bhoys look to compete in the league as well as in the Europa League this season, but he has already told the club's official website that he is looking towards the January transfer window.
A winger may be on Deila's shopping list in the New Year, and Norwegian press believe that he has already identified a potential target.
Adressa believe that Celtic scouts have been watching Rosenborg matches recently, and are specifically monitoring winger Pal Andre Helland.
The 25-year-old has hit a stunning 22 goals in 23 games this season, and has two caps for Norway having starred for Rosenborg ever since his move from Hodd in July 2013.
A left winger with a great eye for goal, Helland will be familiar to his Norwegian compatriot Deila, who would no doubt be able to lure him to Glasgow.
