PARIS: Celtic's hopes of a Champions League berth hang by a thread as the Scots seek to come from behind and oust Dynamo Moscow in Wednesday's second-leg match of the third preliminary round .

Celtic qualified for last season's competition proper as champions.

But having finished runners-up in the league in May to rivals Rangers, they had to go through the qualifiers and a 1-0 home first leg loss last week sees the Hoops already fighting for survival.
