Celtic know they are without James Forrest on Thursday but his replacement should be a surprise – Lewis Morgan.
Scott Sinclair is expected to start in Leipzig but this is something the Germans will have studied.
Sinclair has also not been at his best, whereas Morgan has shown in glimpses that he is a handful.
Games can change careers
In Europe you need to use any weapon at your disposal and Morgan’s surprise entry could be that.
Morgan is yet to score for the Bhoys, or even secure a starting place due to Forrest’s form this season.

MORE CELTIC STORIES
This could be a massive boost to the former St Mirren man’s Celtic career with a big performance.
In fact, successive positive performances could see Morgan tried on the left of the attacking three.
Morgan has excelled for the Scottish youths, proving he can play in unfamiliar environments.

This may be unfair to Sinclair but he’s had a lot of chances already and he’s growing tiresome.
Had he scored on Saturday, then he may have continued on that form – but he missed an open goal.
Europe is somewhere where our forwards need to be clinical and unfortunately Sinclair is no longer that.
This shouldn’t have been a problem in the first place
This all boils down to not being able to replace Patrick Roberts, who was European quality, but it wasn’t to be.
The fact someone of similar quality was not brought in during the summer is another topic of debate.
Roberts was always keen to take men on and often beat them whereas Sinclair has lost that touch.

Morgan is also a similar player to Roberts but is more of a physical unit than the former Celt.
In his St Mirren days, Morgan was known for scoring goals out of nowhere and Celtic need that in Europe.
Linking up with Tom Rogic, who has match winners in his locker, brings more goals to the team from different areas.
It may seem harsh on Sinclair, and his experience could be key if he plays and hopefully he breaks his rut.
However, times change and players have to move on and this is Morgan’s chance to show what he can do.
