I picked them and never backed them at 40/1 after watching a good lot of pre season games so from my point of view I hope they fall short but they are a serious team, my only concern is there squad isn't as strong as some and they are prone to having a player or two missing from suspension/injury at this time of year.
No chance mate but there's slim possibility. Ever since Lionel Messi earned his official FIFA Ballon d'Or trophy back in 2010, Atletico Madrid haven't won any match against Barcelona since 20/09/10.
I'll revert my previous answer, now they hold a 50-50 chances in winning their very first CL title in years!
