HYS: Who should start at centre-back vs Astana?

Celtic will look to continue their march towards the Champions League proper with another strong result against Astana tonight.

The Bhoys surged clear of the Kazakhstan outfit in the first leg, netting five times without conceding any potentially decisive away goals.

It will be a much tougher match at the Astana Arena, however. Celtic have travelled to the other side of Europe and now face a bit of a crisis at the heart of defence with a number of centre-backs out injured.

Dedryck Boyata and Erik Sviatchenko are both sidelined, which saw Nir Bitton fill in at centre-half and perform exceptionally well during the first leg.

But the midfielder-come-defender is now a doubt after suffering an injury against Kilmarnock. So, Celtic fans, would you take another gamble on Bitton, put 19-year-old Kristoffer Ajer into the starting line-up to partner Jozo Simunovic or move Mikael Lustig into the heart of defence?
