It might seem harsh to call Nicolas Kuhn a surprise package in the Celtic ranks this season given Brendan Rodgers spent £3m to prise the winger from Rapid Vienna in January.
The move created little fanfare or excitement, but 10 months later the 24-year-old has become one of the most important players in the Celtic team and is being linked with a move to the English top flight.
His player-of-the-match performance in a 3-1 victory against RB Leipzig at Celtic Park on Tuesday will do nothing to cool that interest either.
Kuhn scored two goals and played a key role in setting up the third as Celtic came from behind to win a Champions League game for the first time since 2007.
