Jablonec manager Petr Rada is crossing his fingers that his stars can handle a 60,000 strong Celtic cauldron.
But he admits there's a chance the Europa League atmosphere in Glasgow's east end on Thursday night proves too much to handle.
The Czechs are chasing after Ange Postecoglou's side took a 4-2 lead from the first leg.
It will be rocking at Celtic Park with a full house on the cards for the first time since before the pandemic.
Rada hopes his players won't wilt in the magnitude of the game and said: "It’s hard. Apart from Tomas Hubschman and Vaclav Pilar, no one has performed before such a large number of fans. If someone is scared, it will be bad.
"When there are 60,000 people here, it is possible that it may leave traces on someone.
"We have pride and we must show it. There can be a lot of things happening in football, but we have to be honest, the first result was not favourable for us.
"We will try to play a better role and be dangerous. Our performance must be collective, players should be motivated by the stadium and the quality of the opponent.
"We respect the quality of the opponent, it will want performance at the limit.
"It doesn’t make sense to defend after the first leg, so we have to be more active than at home and take the game to Celtic – there is nothing else to do."
