Celtic trained in the Tofiq Bahramov Stadium in Baku on Tuesday evening in preparation for today's Champions League qualifier against Qarabag.
Ronny Deila's side hold a 1-0 lead from the first leg at Parkhead last week, when a late header from former Manchester City defender Dedryck Boyata proved decisive.
A place in the Champions League play-offs awaits the winners and Deila has played down concerns about the state of the pitch in Azerbaijan.
He said: "It is not a perfect pitch but this is how it is in football - sometimes you have different conditions and you have to handle that.
"Since coming to Celtic I have been impressed with the players and how they handle different situations. It will be no trouble on Wednesday. Everything has been perfect - the plane journey was shorter than normal, the hotel is fantastic and it will be good that the sun will be away.”
