Ladbrokes have offered a host of specials surrounding events more likely to happen than Celtic beating FC Barcelona.
US Open champion Andy Murray is more likely to win the next two Wimbledon tournaments on the bounce than Celtic to beat the Spanish giants.
Just to exemplify the mammoth task Neil Lennon's side will face as they bid to defy odds of 20/1 at the Camp Nou, the bookies also offer shorter prices about Scotland breaking away from the pound (10/1) or more than 70% of Scots voting for independence (14/1) in the upcoming referendum.
Lionel Messi also goes into the match with the shortest hat-trick odds of all time (3/1) while it's just 4/9 he outscores the entire Celtic team with
Ladbrokes. Messi can be backed at 66/1 to break the existing Champions League record by scoring 6 or more goals in the match.
Finally, if there was any other reminder as to the size of the challenge Celtic face just getting near the Barcelona goal, they are only 9/4 not to register a single shot on target during the whole match. For a typical SPL fixture, that price would be at least 66/1.
Alex Donohue of Ladbrokes told LiveSport.ie: "Should Celtic defy the odds it would rank as one of the biggest Champions League upsets of all time. We reckon there's a better chance Salmond and co break away in style with a new currency than them getting a result."
He added: "When it comes to Messi's goals it's simply a case of how many. We've never known shorter odds for a player to get three in a game like this."
