Celtic are weighing up a January move for Slovenian international striker Andraz Sporar.
The Parkhead club sent scouts to watch the £5million-rated forward score in Slovan Bratislava's 4-2 home defeat to Braga in the Europa League on Thursday night.
Under contract until 2023, the 25-year-old has seven goals from 17 appearances this season.
Sporar claimed five goals in a Europa League group where Slovan Bratislava finished third behind Wolves and Thursday's Portuguese opponents.
A former record signing for a Slovakian club, Sporar also scored for Slovenia as they ended Poland's 100-per-cent record with a 2-0 win in their Euro 2020 qualifier in September.
Neil Lennon is keen to secure a quality back-up to Odsonne Edouard in the January transfer window after a recent injury to the £9m man left the Celtic manager with a dearth of alternatives.
