Former Celtic assistant John Collins believes the club must resist the temptation to cash in on key players before this month’s Champions League play-off against LASK. With Champions League qualification worth around £40 million, taking that gamble would be difficult to justify. “It’s not as easy as it sounds but I’d like to think Celtic won’t be selling any of them before the Champions League qualifier. “If you ask any Celtic fan, they want to be with the big guns in the Champions League. Replacing that level of consistency this close to a Champions League play-off would be a major challenge, no matter how much money arrives.
