Here's the odds.
Barcelona 1.27
Levante 11
I consider this a big odd for Barcelona because it's a sure bet as there is no way Levante is going to get a point at Camp Nuo. If not that we don't treat gambling like conventional businesses where profits are calculated in percentages, standing Barcelona in this match will return 27% as profits, something you can rarely get in most businesses. By the time we start approaching gambling this way, there will be serious improvements in rate at which people win. The match will likely end in many goals because Barcelona are in good scoring form.
The odds means that sportsbook does not think Levante has any chance to beat Barcelona especially after Barcelona began this season with a big win and very impressive performance. From result to playing style, Barcelona has potential to defend their title in La Liga and such a weak opponent like Levante is not enough to stop Barcelona and get any point.
Challenge for Barcelona is maintaining good performances and results in a long season and avoid exhaustion in late of season that, if happens, can cost them La Liga title because Real Madrid are strong, ambitious and very experienced to take advantage of such mistakes from Barcelona to take over a first position and get a league trophy.
