Ramon Vega admitted his side were very fortunate to still be chasing the domestic Treble after their 2-2 draw at Dunfermline in the Tennent's Scottish Cup.
The Pars gave Celtic some nerve-jangling moments before Barry Nicholson secured a replay at Parkhead in the dying seconds.
But Vega is hoping that Lady Luck will not be required in the replay.
"I think we are very lucky that we're still in the cup - but we're still in the competition," said Vega.
"Dunfermline are a very good side and very hard to play against, but I hope we can get through.
"But I think we're very lucky to still be in it because they had a great chance after they equalised - so I'm very happy.
"It's always difficult playing in the cup because everybody wants to get through to the next round, so it was very hard and shows that the replay won't be easy at all."
