Looking for sharpness and formation variations

After a solid, if not unapproachable, home win last week, expectations are high that Celtic will qualify for the next round of the Champions League qualifiers in some comfort tonight.  Beyond the result, the area of most interest is the increase in sharpness, particularly in front of goal.

A week is a long time in preseason.  The players will be rested after the first leg and have had more conditioning sessions before leaving for Iceland.  Pay attention to any changes in formation.  Ronny slipped into a 4-4-2 briefly early in the second half last week.  I expect him to experiment a bit like this tonight.
