Celtic appear to have hit something of a Champions League wall in recent seasons, with the Scottish Champions unable to recapture the form of their glory years and push deep into the latter stages.

A couple of shrewd signings here and there and you could easily see the Scots punching above their financial weight once more.
With that in mind here are the FIVE players for Celtic to look at to bolster their Champions League push next season.
