The third round is still to come and Celtic will know it won't be easy but the teams they can face in the final round have been decided.
The draw takes place before the third round even begins and the Hoops will need to be wary of a couple of teams - but you expect that in the Champions League.
There is, of course, the chance of another game against Rosenborg after the Norwegian champions but that would be one they would be confident of getting through.
The final teams were decided on Wednesday night and include some tasty ties.
Neil Lennon will be hoping for a tie that doesn't see his side travelling half way round the world but there is potential for that to happen.
Here's all you need to know about the draw.
When is it?
The draw will take place in Nyon on Monday, August 5. It will take place at 12pm CET, which means an 11am start here in Glasgow.

Who can Celtic face?
As already mentioned, Celtic can take on Rosenborg once again. The Hoops are seeded for this round so that means they will avoid the likes of Ajax, PAOK, Red Star Belgrade and Dinamo Zagreb.
But it doesn't mean the games will be easy. They could face a trip to Switzerland to take on Young Boys of Berne. A daunting journey to Azerbaijan is also possible with Qarabag taking on APOEL in the third round.
Slavia Prague and Maribor are the other two sides in the hat.
