Former Celtic star Nicolas Kuhn has been placed on the transfer list after he was left out of Como's squad entirely.
The German winger cost the ambitious Italian club £17 million last summer after just a season at Parkhead.
But his spell in Serie A has been a major disappointment after just six starts last season. He netted just once against Torino, made only one assist and lost his place in the team.
And he was left in no doubt about his current position in manager Cesc Fabregas's plans after he was left out entirely of Como's matchday squad for their 1-1 draw at Udinese on the opening day of the top flight in Italy.

Kuhn, 26, is one of six players made available for transfer by Como as they reshape their team for their first-ever Champions League attempt.
He will leave the club along with Alessandro Gabrielloni, Ignace van der Brempt, Luca Mazzitelli, Matthias Braunoder and Ivan Azon.
Reports in Italy have suggested Kuhn has attracted interest from clubs in his German homeland and in Austria and would be able to leave for a considerably lower fee than the £17 million Como splashed out on him.
