However, Burley is sympathetic towards the player's tough schedule and will consider substituting players off before the end o f the match.
"Communication is very important and I appreciate it's been a heavy schedule - it's been especially hard for the Old Firm.
"I want a strong squad and the right result against Croatia. It is important as it is my first match.
"Would I take players off early? It is something I would look at. I'm sure there will be one or two feeling the heavy schedule," added Burley.
